K&N diesel air intake system, number 63-1568, includes a performance diesel air filter and a roto-molded air intake tubes for increased power without sacrificing drivability

2013-2016 Dodge Ram Cummins diesel trucks are equipped from the factory with restrictive disposable air filters housed in an innovative factory air filter box. Dodge Ram calls this new diesel air filter box technology “Ram Active Air” which is a dual-inlet type diesel air filter box with the ability to vary the source of incoming air. In normal driving conditions air is drawn from a protected source under the hood. As under hood temperatures rise, the Ram Active Air filter box switches to a sort of cold air intake system drawing air from directly behind the truck’s front grille. Ram developed this system to combat power loss in hot, dry, up-hill conditions when temperatures under the hood have been shown to climb to extreme levels.

By retaining the factory Ram Active Air filter box, 2013-2016 Dodge Ram Cummins diesel performance can be increased quickly while maintaining factory appearance

K&N Air Filters has stepped in with a K&N diesel air filter and roto-molded high-density polyethylene diesel air intake tube to improve 2013-2016 Ram 2500 and Ram 3500 6.7-liter Cummins diesel performance over the factory design. This diesel air filter and diesel air intake tube is packed into an all-inclusive K&N diesel air intake system 63-1568. Extensive testing was performed, and each time it was apparent that the 2013-2016 Ram 2500 and Ram 3500 6.7-liter Cummins diesel equipped trucks performed better, and without sacrificing drivability, by retaining the stock Ram Active Air filter box.

On the dyno, 63-1568 produced an estimated additional 14.65 horsepower at 2500 rpm and a massive 23.86 pound-feet of torque increase at 2122 rpm over the factory diesel air intake

Testing showed that the major points of Cummins 6.7L diesel performance restriction were eliminated by replacing the disposable diesel air filter with a K&N high-flow diesel air filter 33-5005, and by swapping the convoluted factory air intake tube with a new roto-molded air intake tube. K&N Air Filters was able to see a significant improvement in 2013-2016 Ram 2500 and Ram 3500 6.7-liter Cummins diesel performance with increased horsepower and torque output. On the dyno, 63-1568 produced an estimated additional 14.65 horsepower at 2500 rpm and a massive 23.86 pound-feet of torque increase at 2122 rpm over the factory diesel air intake system when installed on an otherwise stock 2013 Ram 2500 6.7L Turbo Diesel.

Testing was performed on K&N diesel air filter 33-5005 showing a 99.35% overall efficiency rating to guarantee high airflow without sacrificing diesel engine protection

K&N retained the stock diesel air filter box with Ram Active Air technology because it was evident that Dodge Ram engineers paid special attention to inlet air temperature as it travels into the 6.7-Liter Cummins Diesel engine. Cooler air promotes more efficient combustion and the ability of an engine to work efficiently is essential to maintaining peak diesel performance. The engine control unit (ECU) in a modern diesel pickup can adjust engine performance as air temperature increases forcing the engine to run more conservatively and make less power. This means diesel air filter and diesel air intake placement is important to assure proper flow, temperature, and quality of incoming air for peak diesel performance.

When K&N engineers design a diesel air filter much consideration is put into improving diesel performance without sacrificing engine protection with a K&N diesel filter. K&N diesel air filter 33-5005 is built to higher specifications than our standard automotive air filters. This K&N diesel air filter is made with 2-inch deep pleats for a large surface area and six layers of cotton to achieve high levels of filtration efficiency. K&N performs filtration efficiency testing following the internationally recognized ISO 5011 protocol to guarantee that a K&N diesel air filter will provide high airflow without sacrificing engine protection. K&N diesel air filter 33-5005 was shown to have a 99.35% overall efficiency rating.

Retaining the stock Dodge Ram Active Air filter box makes installation of K&N diesel air intake 63-1568 a breeze. With simple to follow instructions and no need to make any other modifications to the vehicle, you’ll quickly be back on the road with more horsepower and torque for hauling, towing, or every day driving.

“I’m really happy with the way the season went,” Hayden said. He continued to say “We’ve been consistent and fast, and we were on the podium at just about every race. This was our first year together and I’m really proud of my team.”

Race two on Sunday at New Jersey Motorsports Park saw Josh Hayes out front of the pack once more with a nearly 2.5 second lead. However, Hayes made a mistake on lap four going off track and dropping back to third place. Hayes was able to charge his way back up to the front eventually claiming the win with Team Yoshimura Suzuki Factory Racing teammates Roger Lee Hayden and Martin Cardenes bringing up second and third respectively.

After the final race, pre-season title hopeful and Team Yoshimura Suzuki Factory Racing rider, Martin Cardenes said “This was a tough weekend. The track is very physical. I wanted to finish a little higher on the podium on Sunday but third was the best I could do. I’m very happy for me and the Yoshimura Suzuki team to finish on the box.” Cardenes made the AMA Pro Superbike podium four times this season and finished sixth overall.

Roger Lee Hayden finished out the 2014 AMA Pro Superbike season strong with five straight podium finishes barely edging past Yamaha rider Cameron Beaubier for the runner-up position in the championship points standings. “This weekend was a good way to finish the season,” said Hayden. “I rode as hard as I could, every lap. This was my first time to finish second in points, and I learned a lot this year. We can all be proud of this.”

Team Yoshimura Suzuki Factory Racing rider Chris Clark also experienced a breakthrough AMA Pro Superbike season this year. Clark earned his first Superbike podium position and finished fourth in the points race, just one point ahead of David Anthony. “Overall, it was a really incredible year,” said Clark. “I have to thank the whole Yoshimura Suzuki team for the opportunity to race and for providing me with a great bike like the Yoshimura Suzuki GSX-R1000.”

Greg Pursley had the fastest time in qualifying during the Energy Solutions Utah Grand Prix in Tooele, Utah taking home his twentieth 21 means 21 presented by Coors Brewing Co. Pole Award

James Bickford, in the number 6 Sunrise Ford of Fontana race car, challenged Greg Pursley on lap 43 of the NASCAR K&N Pro Series West Utah Grand Prix, shortly before Pursley spun out

It had seemed as if the driver of the number 26 Gene Price Motorsports Ford, Greg Pursley, was on his way to a fourth win at Miller Motorsports Park in Tooele, Utah. Pursley had the fastest time in qualifying and took home his twentieth 21 means 21 presented by Coors Brewing Co. Pole Award. Pursley dominated the first 43 laps of the 50 lap race on a 2.2 mile long road course at Miller Motorsports Park.

On that fateful 44th lap of the NASCAR K&N Pro Series West Utah Grand Prix race Pursley got into a battle with number two qualifier James Bickford. Eventual race winner David Mayhew was close behind the battle for first. As Pursley and Bickford came into turn one on lap 44 Pursley made contact with a lapped car sending Pursley and the number 26 GPM/Star Nursery/Real Water Ford into a spin.

Pursley made contact with lap traffic and as David Mayhew described, they all ended up in the dirt with Mayhew gaining the lead and winning the race at Miller Motorsports Park

James Bickford momentarily gained the lead in the number 6 Sunrise Ford car, but must have lost some steam as David Mayhew and Sunrise Ford teammate Dylan Lupton quickly made it past him. Mayhew was able to hold Lupton off for the remaining seven laps earning his first NASCAR K&N Pro Series West road course victory.

Prior to his win at the Energy Solutions Utah Grand Prix, Mayhew’s best finish at Miller Motorsports Park had been fifth place back in 2011. “Every time we’ve been here we’ve had a flat tire,” said Mayhew. Luck seemed to be on the Atascadero, California native’s side this time. Of his pass during Pursley’s spin, Mayhew said “At the end we all ended up in the dirt. I got lucky and came out on the good end of that stick.”

Greg Pursley’s fourth place finish was just enough to maintain his 15 point lead over Dylan Lupton in the points championship. Lupton’s second place finish increased his lead over third place, Brandon McReynolds, ever so slightly. The NASCAR K&N Pro Series West championship is still up for grabs as two races remain in the 2014 season. The next race will be at the All American Speedway in Roseville, California.

Mayhew, and Sunrise Ford of Fontana driver Dylan Lupton, made it past James Bickford never looking back and eventually won the Energy Solutions Utah Grand Prix by 1.022 seconds

A K&N automotive air filters diesel air filter or diesel air intake can improve diesel performance while working, towing, or every day driving in your diesel powered pickup truck

Replacing the stock auto air filter with a K&N diesel filter, like the K&N diesel air filter for 2003-2009 Dodge 2500 and 3500 Cummins 5.9L diesel models, can improve diesel performance

It wasn’t long ago that the term “Diesel Performance” would have been considered an oxymoron. A diesel engine has several advantages over a typical gasoline powered internal combustion engine but until recently performance was never considered one of those advantages. In the automotive world diesel engines have been known for their fuel economy, torque production, and longevity. In Europe diesel powered passenger cars are popular because a diesel engine will burn less fuel than an equivalent gasoline engine doing the same amount of work. Heavy duty diesels, such as semi-trucks, busses, and recreational vehicles have also exploited the fuel efficiency advantages of the diesel engine, but because of the distances these vehicles drive the ability of a diesel engine to last twice as long as a gasoline engine plays a major factor in choosing a diesel power plant.

Modern advances in diesel performance technology have made diesel engines widely accepted as a positive alternative to gasoline burning engines. Gone are the days when a diesel was looked down upon for being slow, noisy, and dirty. Improvements in direct injection and forced induction have helped cure the arguments for diesel engines being slow. The issue of diesel noise, or “diesel clatter”, has been addressed with the improvements in direct injection, and electronic engine controls, as well as higher-quality diesel fuels. Tail pipe emissions from diesel powered vehicles have been improved in modern diesel engines by reducing waste fuel. It’s the wasted fuel in a diesel engine under load that produces black smoke, and this has been nearly eliminated with modern electronic engine and emissions controls.

Diesel performance can be further improved by installing a K&N diesel air intake system such as number 77-3063KTK as shown on this 2004 Chevrolet Kodiak CK4500 6.6L V8 Diesel

To keep inlet air temperature within factory specifications the K&N diesel air intake for 2010-2012 Dodge Ram 2500 and 3500 Cummins 6.7L diesel models uses an enclosed air filter box

While modern advancements in diesel technology have made a world of difference, these same advances have made improving diesel performance more difficult. The basic principal behind increased diesel performance is to increase air in the cylinders allowing more fuel to be burned and more horsepower and torque to be produced. Forced air induction, like that provided by superchargers and turbochargers, accomplishes the task of increasing air pressure loaded into the cylinder. However, most diesel engines are already equipped with forced induction from the factory.

That’s where K&N air filters steps in with a diesel air filter or diesel air intake to improve diesel performance over the factory design. Most diesel cars and trucks are equipped from the factory with restrictive disposable air filters which are housed in a confined factory air filter box. After that, the air is routed through convoluted factory air intake tubing which disrupts, and can even impede, airflow into a diesel engine. By eliminating some or all of these points of restriction with a K&N diesel air filter, or diesel air intake system, K&N Air Filters is able to improve diesel performance by increasing horsepower and torque output.

K&N performs diesel air filter and diesel air intake testing to ensure a K&N diesel filter provides engine protection, improved diesel performance, and operates within factory specifications

K&N designs a diesel air filter to higher specifications than a standard K&N auto air filter with deeper pleats for more surface area and more layers of cotton in different grades

Eliminating the restrictive disposable diesel air filter, constricted factory air filter box and the convoluted air intake tubing will reduce restriction and improve efficiency, but that is just part of the diesel performance equation. K&N engineers pay special attention to air temperature as it travels into the engine. Because cooler air has more mass it promotes more efficient combustion. The ability of an engine to work efficiently is essential to making power and improving diesel performance. The engine control unit (ECU) in modern diesel pickups and cars can adjust engine performance as air temperature increases forcing the engine to run more conservatively and make less power. This means diesel air filter and diesel air intake placement is important to assure proper flow, temperature, and quality of incoming air for peak diesel performance.

When K&N engineers design a diesel air filter or diesel air intake much consideration is put into improving diesel performance without sacrificing engine protection with a K&N diesel filter. Normally a K&N diesel air filter is built to higher specifications than our standard automotive air filters. The typical K&N diesel air filter is made with deeper pleats for more surface area and more layers of cotton in different grades to achieve higher levels of filtration efficiency. K&N performs filtration efficiency testing following the internationally recognized ISO 5011 protocol to guarantee that our air filters will provide high airflow without sacrificing engine protection..

Diesel air filter filtration efficiency isn’t the only aspect of engine protection. A K&N diesel air filter, as well as a K&N diesel intake, undergoes airflow, dynamometer, and over-the-road testing to ensure that our product will improve diesel performance without causing drivability issues. Modern diesel engines are required by federal law to run within such narrow operating parameters that K&N engineers must be careful to increase diesel performance without upsetting electronic engine controls. K&N does its homework to ensure a K&N diesel air filter or diesel air intake system can provide improved diesel performance without the need for further modifications.

K&N has been committed to improving diesel performance since the 1990’s when diesel engines became popular in full-size pickup trucks. A listing of K&N diesel air filter and diesel intake offerings can be found on the Diesel Filter Performance - Air Intakes & Air Filters page, or use the K&N product lookup tool to find a diesel air filter, or diesel air intake for your vehicle.
