The K&N 63-1136 air intake has an RU-5064 rubber air filter fully encased in a full filter housing

The company became a major player in the ATV industry when it introduced its Ranger Utility Vehicle (UTV) in 1998. The Ranger featured Polaris exclusive On-Demand six-wheel drive, a rear cargo box and side-by-side seating to accommodate two adults. It became a mainstay vehicle for hunters, farmers, ranchers, and homeowners who work on their land and outdoor enthusiasts who wanted to traverse the rugged off-road terrain for recreation.

In 2007, Polaris unveiled the RZR, a UTV meant to challenge Yamaha’s Rhino, which had helped to win a major share of the UTV market for the Japanese manufacturer.

The RZR did not only challenge the Rhino, it actually redefined what a UTV was. The vehicle looked different than any other UTV in the market and it was specifically designed to offer off-road fun to riders. The vehicle was only 50-inches in width, which permitted it to go on trails where no previous UTVs could go. Many trails had a maximum width of 50-inches and most UTVs were simply too wide to ride them.

It wasn’t long before the RZR was one of the most popular all-terrain vehicles in the market and it helped Polaris become the leading UTV manufacturer.

The most recent RZR vehicles to come from Polaris are the 2016 RZR XP Turbo and RZR XP 4 Turbo EPS.

A 925cc, 4-stroke, twin cylinder, double overhead twin cam engine with electronic fuel injection powers both the RZR XP 4 Turbo EPS and XP Turbo. The engine delivers 144-horsepower. What’s unique about it is that it delivers the same horsepower at higher elevations.

Typically, a UTV engine will lose about 3.0% to 3.5% of its horsepower for every 1000 feet gain in elevation. So, for example, at 7,000 feet, a non-boosted 100-horsepower engine is actually delivering an output power of between 75.5 to 79-horsepower. The Polaris ProStar Turbo engine is not affected by higher elevations because it includes the turbocharger.

The engine can achieve 0-60-mph (0-96.6-kph) in 5.89-seconds and offers more than 45% more torque than other engines. In fact, this engine is the most powerful side-by-side engine available. In order to achieve its extreme performance, the engine includes a number of high performance parts including forged pistons, an upgraded 270-degree firing order forged crankshaft, high strength connecting rods, a closed deck cylinder, sodium filled exhaust valves and a new oil lubrication system. It performs consistently in all temperatures because it includes a new liquid charge air cooler with front-mounted radiator and high-flow electric pump.

To manage the massive power of the turbocharger, the engine also includes an engine management system with knock detection, boost control and a high-flow return style fuel system. All of this ensures that the engine performs at maximum power in all conditions, altitudes and temperatures.

The RZR XP Turbo EPS also features a suspension system with highly tuned FOX Podium® Internal Bypass Shocks that include large diameter bodies (3-inches/7.6-centimeters in the rear, 2.5-inches/6.4-centimeters up front), adjustable remote reservoirs and increased fluid capacity for dramatic improvement in heat dissipation, fade resistance, and durability.

To complement the shocks, Polaris includes bigger coil-over springs. Also included are 29-inch (73.7-centimeter) Maxxis Bighorn tires on 14-inch (35.6-centimeter) cast rims.

The vehicle features a 90-inch (228.6-centimeter) wheelbase, 18-inches (45.7-centimeters) of rear travel and 13.5-inches (34.3-centimeters) of ground clearance.

K&N has recently introduced the 63-1136 air intake kit specifically for the 2016 Polaris RZR XP 4 Turbo EPS and Polaris RZR XP Turbo. Dyno tests confirm that the kit offers an estimated boost of 4.09-horsepower at 35.8-mph.

The kit includes a K&N washable and reusable RU-5064 universal rubber air filter. It features a multilayered cotton gauze media that has been treated with a special grade of oil, which makes the cotton strands very sticky.

K&N also offers the 99-5000 filter care service kit that is specially formulated to cleanse and rejuvenate the air filter so that it can be used over and over again for the life of the vehicle.

K&N is so sure of the quality of the air filter, it backs it with a 10-Year/Million Mile Limited Warranty. The document promises that the air filter will perform for up to 10 years or 1,000,000 miles without needing replacement.

The air filter is totally encased within the air intake kit. The kit also includes a free-flowing aluminum intake tube, nine stainless steel clamps and two couplers.

The air intake is designed to dramatically reduce intake restriction because it provides a smoother and straighter path for the airflow to reach the engine. This allows the engine to breathe more air than the factory air intake assembly permitted. The result is a boost in horsepower, acceleration, throttle response, and improved engine sound.

The K&N 63-1136 air intake kit can be installed in about 90 minutes using common hand tools. It is designed for the following vehicles:

Kathy waits out the weather in her trailer at Virginia Motorsports Park

Nonetheless, Kathy and her husband Kevin, who run the team from their shop in Lima, Ohio, see 2017 as their best opportunity to take the Top Dragster championship in the 1/8 mile PDRA series. Last year Kathy finished fourth in the championship and was only able to attend six of nine races. In addition she’ll be running at NHRA Divisional and National events not just for the 1/4 mile experience, but also to further support her marketing partners.

While she was knocked out in the second round at the first PDRA event of the year, at the NHRA Divisional at VMP she qualified second. The event couldn’t be completed so it will be run as part of the August race. In the meantime, Kathy made it to the semifinals at the NHRA Nationals in Atlanta.

Kathy, alone with her thoughts before her run, planning out each move to the microsecond

Kathy got her start drag racing like most kids – competing in her father’s Nova. While working to establish her career in broadcasting didn’t leave much time for drag racing, but she was slowly drawn back in. First it was racing her own Camaro (on which she installed her first K&N filter), and then through various steps ended up working for Frank Hawley's NHRA Drag Racing School. While working for Frank she earned her Top Alcohol license and she was on her way.

Now her sites are set on becoming one of the top 1/8th mile Top Dragster racers in the country. And she has the car to make it happen.

Warming up her Mickey Thompson slicks before a run. Top Dragsters run automatic transmissions.

Stan started with off with a Brodix Big Block punched out to 547 CID. Heads are aluminum B3 units from Brodix as well. Pistons are from J&E and the crank is from, of course, Ohio Crankshaft. Air is drawn through a K&N filter by the F3-121 Procharger, and into the engine via a single-blow-through carburetor.

Upon hearing the motor start for the first time a former team member referred to its sound as "thumpy goodness." Some of that is due to Kevin, who fabricates the headers himself out of Borla pipes. As the President of Performance by Fisher, a custom exhaust and repair facility in their hometown of Lima, he certainly brings the skills to the job. Once the welding is done the headers receive an Armor Coat ceramic coating.

Power is driven back not through a direct drive using a series of clutches like a Top Fuel dragster, but rather a heavily-modified Abruzzi two-speed Powerglide with an aluminum torque converter. The chassis is an American Race Cars 272-inch wheelbase dragster out of Millbury, OH (see a trend here?).

The ultimate selfie. Actually a frame grab off a video of one of Kathy's runs. Trade seats anyone?

As performance by Fisher is also a independent repair garage that focuses on performance work, Kevin and his crew install K&N filters on customer cars. As Kathy says, "use ‘em, love ‘em, sell ‘em."

Travis Miller won the first NASCAR K&N Pro Series East race of his career at South Boston Speedway

Miller, who started in the second row, passed rookie Chase Purdy for the lead on lap 59 after the only restart of the race. There was one caution for four laps, from laps 55-58.

"I wasn’t quite sure how it was going to work there," Miller said. "That was probably the winning move on our part."

Chase Cabre won the pole and led for the first 19 laps of the race. Purdy took the lead on lap 20 and was out front for 39 laps. Cabre fell back and finished in seventh place. Purdy crossed the finish line in second place.

"He was definitely faster than me at the end of the race," Miller said about Purdy. "He drove me really good and I actually cut him off once or twice. I definitely appreciate him driving me clean even after I did that. All in all it was a good race."

Purdy posted his first top five finish and second top 10 in five K&N Pro Series East races.

"That was down to the wire," Purdy said. "Hats off to my crew. The work they do in the shop all week doesn’t compare to what you see here. They work their butts off. They give me a fast race car and that was just hard racing right there."

Travis Miller led 40 laps of the NASCAR K&N Pro Series East race at South Boston Speedway

"That was the game changer right there," Miller said. "It was really hard to pass on the bottom here. That’s what won us the race, that restart."

Todd Gilliland, the 2016 K&N Pro Series West champion, finished third. Dillon Bassett was fourth, followed by Harrison Burton in fifth.

Burton took a 14-point lead over Gilliland in the K&N Pro Series East race after the first race at South Boston Speedway. Purdy was third, 24 points behind Burton.

K&N cold air intakes are designed to feed your engine more air thus giving it more power

The paper OEM filter and corrugated air tube that likely came with your truck from the factory worked well for what the engineers needed. However, enthusiasts are often left scratching their heads and asking, “who designed it like this?” Unfortunately, engineers are under a lot of constraints when manufacturing a vehicle. Everything from time and money limitations to keeping the sound levels and power numbers at the correct levels often plague engineers during the build. That is why companies like K&N Engineering offer solutions like cold air intakes.

The install of a K&N cold air intake takes around 90 minutes and can be done with common hand tools

Another part of the cold air intake equation, besides getting more air into the engine, is the quality of the air. As stated before, these systems typically have a heatshield or air box to separate the air filter from the engine bay. The air in the engine bay is quite warm, while the outside air is relatively colder. Cold air has more oxygen molecules than warm air. The mass airflow sensor in your vehicle can detect the temperature of the air and inject more or less fuel as necessary.

One of K&N's newest series of cold air intakes is the Blackhawk Induction line of intakes

K&N offers several different cold air intakes for vehicles depending on individual needs. These vary from a traditional oiled cotton media to a non-oiled synthetic media. The choice is yours. So if you need a boost in power and the ability to filter out dirt and dust before it reaches your engine, check out K&N to see all the intakes and other products they have to offer.

The K&N 77-series air intake system is designed with both style and performance in mind

The 2016-2017 Land Cruiser utilizes Toyota’s well-proven full-time four-wheel-drive system. Choice of either the high- or low-range are made selected by turning a console-mounted dial. The center mechanical differential is a Torsen torque-sensing unit set to a 40/60 front-to-rear torque split, but has the ability to self-adjust if more power is needed at one end or the other. Both brake and throttle are controlled by Toyota’s Active Traction, if the situation demands. Meanwhile the driver has his or her choice of settings (Multi-Terrain, Crawl, Downhill Assist, Mogul, and Hill-Start Assist) to optimize performance for the terrain being traversed.

While the Toyota Land Cruiser’s 5.7L V8 produces 381 horsepower and 401 lb-ft of torque, one has to recall that the motor is pulling around nearly three tons of mass. That’s part of the Land Cruiser’s strength, but also one of its weaknesses. Go back to the turn of the century and Chevrolet was producing 350 horsepower out of the technically inferior 5.7L LS1 engine.

The heat shield isolates the filter from underhood heat, allowing only cold air to flow to the motor

Cool, fresh air first enters a chrome-topped RF-1044 K&N high-flow air filter positioned within a heat shield that installs into the space of the factory air box. Much of the performance increase can be attributed to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media which offers greater surface area and thus less resistance than traditional filters but provides outstanding engine protection.

Engine protection is provided by a multi-layered cotton material, which filters out fine particles of dirt and dust that could damage your engine, to ensure a long engine life. Each design is verified through K&N’s in-house filtration testing lab, which adheres to ISO 5011 standards, ensuring that K&N filters provide high airflow without putting engine protection at risk.

Everything needed to install your new K&N 77-series performance air intake is included in the box

The intake tube of a K&N cold air intake significantly reduces restriction to incoming air flow over the stock item, as well as calms power-robbing turbulence. Air passes through an aerodynamically-verified polished aluminum intake tube directly into the engine’s throttle body. The intake tube accommodates the factory mass air sensor, fuel pressure hose, and crankcase vent hose.

Best of all, the K&N intake system can be installed in 90 minutes or less with simple hand tools like a ratchet set, a few screwdrivers, and a couple of wrenches. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to your car that come included in the package.
