Josh Toth will join the 2017 US Junior Trophy Team

“We recently received the good news that Josh Toth will be joining the 2017 US Junior Trophy Team and representing this great country in France aboard his factory Yamaha YZ250FX,” reported AmPro Marketing Coordinator Brian Elliott.

AmPro is looking to build on the foundation of success that Toth started last year in the International Six Days Enduro (ISDE).

“In 2016, Josh finished the ISDE as the number one club team rider in the world,” said Elliot. “We are excited to see what he can do this year!”

“I rode pretty good in the beginning, but I couldn’t stay off the ground,” said Toth. “I like the mud, so when it started raining I think I got stronger. I’m getting better at this tight stuff and I definitely had a lot of fun.”

The podium finish is the Connecticut rider’s best result to date. Toth’s success at the Cherokee National Enduro bodes well for his continued development in the sport.

To get more performance from your 2014-2017 Yamaha YZ250, install the K&N YA-4514XD replacement air filter. Check K&N’s online application tool to confirm the correct filter for your motorcycle.

The Ford Focus RS is a popular option for automotive enthusiasts and K&N can help add power

Chassis dynamometer testing verified an estimated increase from 224.46 horsepower to 258.47 horsepower, as measured at the drive wheels, on the same Ford Focus RS on the same day, with the only change being the installation of a K&N 69-3539TB.

The Focus RS features a 2.3L DOHC turbocharged EcoBoost engine delivering an astonishing 350 horsepower stock that can launch it from 0-60 mph in 4.5 seconds, which is just a tick slower than the Ford GT 40 Mk II that won the 24 Hours of Le Mans.

The 2.3L EcoBoost is an all-aluminum four-cylinder engine, with DOHC and four valves per cylinder with Twin Independent Variable Cam Timing (Ti-VCT). Stroke is unusually long for a performance engine at 94 mm versus a bore of 87.6 mm. Intake air is compressed by a Honeywell twin-scroll fixed geometry turbocharger, with engine management by a Bosch MEDG17-I4. Full power comes on a relatively low 6000 rpm, with peak torque at 3200 rpm.

The K&N Typhoon air intake kit can add more than 33 HP to 2016 and 2017 Ford Focus RS

As is the case with virtually all turbocharged engines and virtually all direct injection engines, the more intake air you can feed into the system, the more power the engine will make. In the example of the Ford Focus RS, an additional mass of air fed into the turbocharger is supplementary to what it normally draws, so its output is increased proportionally to the increase in input.

With this increase of air entering the combustion chamber, the electronic engine management of the Focus RS increases the amount of fuel to maintain the proper ratio of combustion. With more air and more fuel, more power is made. And that’s the basics of the K&N 69-3539TB Typhoon air intake system.

The 69-3539TB Typhoon air intake system is designed to fit 2016 and 2017 Ford Focus RS models. The power increase is achieved by replacing the OEM factory air filter, intake tube, and air filter housing with a aerodynamically-verified K&N Typhoon mandrel-bent aluminum tube air intake system, which is designed to dramatically reduce air flow restriction as it smooths and straightens air flow.

Included in the 69-3539TB Typhoon air intake kit is a K&N high-flow RU-5163 air filter and a heat shield that installs in the original factory mounting location. Much of the horsepower gain can be attributed to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media -- which offers less resistance than traditional paper filters. The multi-layered red cotton material also filters out microparticles that could damage your engine. Each filter design is verified through K&N’s in-house testing lab, which adheres to ISO 5011 standards, ensuring that your K&N filter provides high airflow without putting engine protection at risk.

This Typhoon air intake is relatively easy to install, typically in 90 minutes of less using common hand tools. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to your Ford Focus RS that comes included in the shipping carton.

The K&N air filter you purchase is designed to last for the lifetime of your vehicle, which K&N guarantees with a 10-Year/Million Mile Limited Warranty.

The K&N 69-3539TB fits the following vehicles:

Jimmie Johnson celebrating his win at the AAA 400 Drive for Autism at Dover International Speedway

"To be here and tie him at 83 wins is amazing," Johnson said. "We just got the tribute helmet. I wasn’t sure how quickly we’d be there (at 83 wins), or if we’d be able to go there and get it done. But, Cale, you’re the man. Thank you for all you’ve done for our sport."

Johnson led twice for a total of 7 laps. Johnson, who was not leading coming down to the 400th lap, was given new life when David Ragan crashed into the wall, causing a restart. Johnson saw his chance, and took it all the way to overtime and crossing the overtime finish line for the win.

"I never thought I would end up here in NASCAR as a kid racing in the dirt out in Southern California," Johnson said. "I was a big Cale Yarborough fan and I remember going to a race in Oklahoma with my parents and my brother.”

Kyle Larson finished in second place, leading for a race-high 6 times and 241 laps. Larson was passed by Johnson on the overtime lap, and lost the chance to pick up his second win of the season. This was Larson’s fifth second place finish of the season.

"It was a good race for us," said Larson. "Obviously, I didn't need that last caution. Yeah, I mean, Jimmie is the best of our time, probably the best of all time.

“Definitely proud of our finish today” Truex said. “I thought we definitely had a shot at the win until that happened, and after that it was just -- we were kind of playing catch-up. At a place that's really difficult to pass, we had to come from about 15th to get to third. Definitely proud of the run, proud of the effort and the car the guys brought here today.”

Martin Truex Jr. continues to lead the Monster Energy NASCAR Cup Series standings with 545 points and 18 playoff points. Kyle Larson is in second place with 536 points and 7 playoff points. Kevin Harvick is in third place with 429 points and 3 playoff points.

The next race in the Monster Energy NASCAR Cup Series will be the Pocono 400 presented by Axalta at Pocono Raceway.

The K&N RK-3946X is a complete replacement intake system for your Harley FL

Well, that’s just what the K&N RK-3946X Street Metal high-flow air intake system can do for your Harley-Davidson FL model. K&N’s dynamometer testing revealed an estimated horsepower gain of over 7.5 horsepower when the RK-3946X was installed on a stock 2015 103 CI Harley-Davidson Street Glide.

That same Street Glide showed an estimated increase in torque of almost 9 foot-pounds at approximately 2800 RPM with the RK-3946X intake. Of course, your performance gains will vary by model, bike set-up, and condition. However, you can expect a noticeable bump in acceleration and power with the RK-3946X intake.

The RK-3946X is designed as a complete replacement for the stock Harley intake and filter. The intake mounts directly to the throttle body with an integrated aluminum internal-run breather system incorporated in a custom aluminum backing plate.

Everything that is needed for easy installation is included in the RK-3946X kit

The “X” in the RK-3946X indicates that the intake features an extra tall air filter design that provides even more air flow and longer service intervals than standard RK-series air intakes. It is a perfect addition to large engine builds or for bikes that have other modifications like a supercharger or tune that will benefit from the significant increase in airflow.

K&N’s legendary cotton gauze filter material ensures that only clean, filtered air makes it to the big jugs on your V-twin. The pleated element is fully washable and reusable and comes with K&N’s 10-Year/Million Mile Limited Warranty. It is pre-oiled and ready to install directly out of the box.

Take a look at the extensive application list below, and consult K&N’s online application search tool for all of your Harley filtration needs.

Shea Holbrook in a light moment before the Canadian Tire Motorsport Park race

Take the Pirelli World Challenge and the K&N-sponsored Shea Racing Honda team. Immediately after their race ended on Sunday they had to load-up and drive from Canadian Tire Motorsports Park in Ontario, Canada, to Lime Rock Park in rural Connecticut, ready to load in on Thursday morning. That’s not much of a break for anyone. But Shea Racing was undeterred and unperturbed.

In Canada, the good news was that Shea Racing's Pirelli World Challenge Touring Car program earned the first victory of the season with Tom O’Gorman driving the new Honda Civic Si, starting from the pole to win Sunday's Touring Car A race.

O'Gorman earned the pole position not through qualifying but by setting the fastest lap in Saturday’s race. In addition, he brought his Honda Civic Si home to a fourth-place finish.

O’Gorman was actually lucky to be in Saturday’s race at all. Several laps into the race, several cars collided and collected O’Gorman as he had the bad luck to be in the same area of the racetrack. The race was red-flagged. The problem that faced Shea Racing is that the Civic Si had not yet reached showrooms so repair parts were extremely limited.

Just as it looked all was lost, a Honda of Canada employee drove by in a new Civic Si. Happy to assist (of course, as A. he’s from Honda, and B. he’s a Canadian) the team start disassembling his street car with the promise they’d put it all back together when they were done. “We basically needed everything forward of the radiator from the passenger car. Body work, arm supports, and various front end parts to put the race car back together again,” O’Gorman said.

Where the weekend had been pretty lucky for O’Gorman, it was hardly the case for new recruit to Shea racing, Sarah Montgomery. On Saturday she barrel-rolled her Civic and while uninjured in the crash, but was unable to answer the bell for Sunday's race. If you’re keeping track, that’s two cars rolled in two weekends.

Team owner and driver Shea Holbrook ran her Honda Accord from 19th on the starting grid to ninth in Saturday's TC race, but then she had her own drama. "What I thought was a tire going down was actually a caliper on fire," Holbrook explained. "Rubber coming off of the rain tires collected in the caliper and caught on fire. No problem except that I couldn't turn the car!"

The entire Shea Racing team was looking forward to a drama-free weekend at Lime Rock, a race that’s run on a tight schedule as racing is not allowed on Sunday at the facility. Everything had to be squeezed into two days.

Tom O’Gorman moved into fourth in the standings with his 2017 Honda Civic Si as he took third after starting fifth. Tom nearly scored a podium finish in Friday’s race as well, but a valve stem was broken in contact with another car in Turn Three, forcing him into the pits with a by-then flat tire.

Team boss and driver, Shea Holbrook, demonstrated her and the Honda Accord’s competitiveness in both Touring Car events. Shea made up three positions from her starting position in Friday’s opening race and gaining five spots over her grid position in Saturday’s event. The tight 1.47-mile race course made passing opportunities hard to come by, but Shea made the most of the opportunities that presented themselves in both races.

“We made some minor handling changes for race 2, which made my Honda Accord virtually flawless,” reported Holbrook. “I was able to put the pressure on a little harder, and I know we could have run higher, but we feel good about our consistency on what was our best weekend of the season so far.”

After two races jammed together the team will have a lengthy midseason break to prepare for its next event, as the Touring Cars do not compete again for a couple months at Utah Motorsports Campus.
