Tai Woffinden lives life sideways. Notice the K&N patch on his right shin.

In keeping with his electric personality, Tai Woffinden, a K&N-sponsored British speedway racer, enthusiastically sums up the form of racing that he loves.

“Speedway is pretty much motorsport in its rawest form,” says Woffinden. “We race 500cc motorbikes that weigh around 75 kg (165 lbs), and they accelerate faster than an F1 car, with top speeds of up to 80 miles per hour. The big difference is we don’t have brakes! The bike just has a throttle, clutch, and one gear. We race on shale-based oval tracks, and you basically power-slide around the corners. It’s pretty gnarly!”

The Early Years

Woffinden’s impressive racing resume dates back to 2006 when he was a 15-year-old racing prodigy. In that first year, he won the Western Australian Under-16 Championship and was named Supporters Rider of the Year.

Over the next few years, Woffinden continued to rack up wins and attract the full attention of the speedway racing world. At the age of 16, he became the British Under-18 Champion and was the youngest rider ever to appear in the British Championship Final.

Rising to the Top

2013 was a banner year for Woffinden. In addition to winning the British Speedway Championship and the Czech Speedway Grand Prix, Woffinden reached the true pinnacle of the sport winning the FIM Speedway World Championship. He did all of this fighting through two broken collarbones. He was named MCN Man of the Year and World Speedway Riders' Association Rider of the Year.

After a solid year including several prestigious titles in 2014, Woffinden returned to the speedway mountain top in 2015. He was the British Champion, the FIM Scandinavian Grand Prix winner, the FIM Czech Republic Grand Prix winner, and ultimately he regained the Speedway World Championship.

The 2017 Speedway World Champion has been a challenge for Woffinden. He has fought through crashes and had dodged serious injury twice in recent weeks. In a freak incident in Sweden, Woffinden narrowly escaped a potentially season-ending injury.

“I just wanted to do another lap because I was feeling good and our next meeting will be back on that track,” Woffinden says. “But it all went wrong! I couldn’t believe it, I got some grip and the bike was pulled towards the fence. I was thrown off the bike and anything could have happened, but I’m fine - thankfully! It was ironic because of the crash I’d had in Poland the week before, but in both cases, it could have been worse so I suppose I have to count myself lucky.”

Woffinden is currently 17 points behind Grand Prix Series leader Maciej Janowski. Supremely driven and ever optimistic, Woffinden says a third world title is still a possibility.

It would be unwise to count Woffinden out of the title race. He possesses a rare combination of determination, toughness, and talent that makes anything possible.

K&N is proud to part of the Tai Woffinden team!

In just its third all-new big twin in 80 years, Harley has unleashed the exciting new Milwaukee-Eight. As Alex Bozmoski, Harley’s Chief Engineer of New Products puts it, “It’s a brand-new motor, tip to tail.” The “Eight” in the new engine’s title indicates the utilization of 8 valves. Interestingly, the octet of valves is actually reminiscent of the power-train of the Harley board track racers of the company’s early years.

To get the most out of the new 107 CI Milwaukee-Eight engine technology that powers much of the 2017 Harley FL line, K&N has developed the K&N 63-1138 air intake. The 63-1138 is designed to enhance the visceral riding experience in a very exciting way. The intake is designed to improve throttle response with a significant increase in clean airflow to the new engine.

In keeping with that visceral riding enhancement theme, the 63-1138 emits an aggressive and satisfying engine growl. When running the 63-1138 the deep breathing Milwaukee-Eight’s intake sound is unleashed.

The performance enhancement that the 63-1138 offers up for the Milwaukee-Eight engine is a direct result of careful engineering. The intake starts with a special billet aluminum throttle-body mounting plate that attaches to a mandrel bent aluminum intake tube.

K&N knows you want your Harley fully protected from the ravages of the road. K&N’s oil-impregnated filter media has been proven over 4 decades of real world testing. Not only will your Milwaukee-Eight engine breathe freely, it will also breathe clean.

The intake comes pre-oiled and ready for a simple, straightforward installation on your Harley FL model. When it is time to clean the element, that process is easily accomplished with a K&N recharge kit like the 99-5000. For added protection and a unique look, the filter element can be dressed in the RC-3680DK filter wrap.

The intake comes in two distinct finishes to complement your Harley’s styling. The 63-1138 is powder-coated in an aggressive black finish. While the 63-1138C features a gleaming chrome finish.

Everything that is needed for easy installation is included in the 63-1138 kit

The 2017 GSX-R1000 is all new, and dominating the sportbike world

The 2017 Suzuki GSX-R1000 is proving itself on the grueling MotoAmerica Superbike race circuit, just as it is on the public streets around the world. The all new flagship Gixxer is a lean, mean, canyon-carving machine whether in the hands of weekend warriors or Superbike stars like K&N-sponsored Yoshimura Suzuki racers Toni Elias and Roger Hayden.

The 2017 GSX-R1000 and the limited-production, higher-spec GSX-R1000R are the latest and greatest incarnations of the legendary GSX-R sportbike line. As Motorcyclist Magazine puts it, “It’s nice to see that the fire is still burning at Suzuki, and the GSX-R1000 is defending its title as the granddaddy of superbikes with more drive than ever.”

Cycle World Magazine continued the praise parade. “It’s an incredibly confidence-inspiring motorcycle overall, and strikes a perfect balance between user-friendliness and raw performance.” CW goes on to declare that the 2017 GSX-R, “could very well be the bike that brings the ‘King of the Superbike’ crown right back to Suzuki’s doorstep.”

MotoAmerica Superbike points leader Toni Elias shows the K&N filter he uses in his GSX-R1000R

There may not be a motorsports segment that is more passionate about squeezing every ounce of performance out of a machine than the sportbike community. That is exactly what both the K&N SU-1017 direct replacement air filter and the race-specific K&N SU-1017R are designed to do.

The SU-1017 is designed for the street with no engine mapping or fuel management modifications needed to benefit from the increase in airflow to the GSX-R’s thirsty inline 4-cylinder powerplant. The SU-1017 is the smart performance choice for everyday riders and weekend canyon carvers.

Performance is taken to the next level with the race and track only SU-1017R. The SU-1017R is designed with a reduced amount of filtration media for the ultimate in airflow. Unlike the SU-1017, the ultra-high performance SU-1017R race filter will require fuel management modifications when fitted in the GSX-R.

K&N Protection for the GSX-R

The application-specific filter body on the SU-1017R fits perfectly in the stock GSX-R air box

For full engine protection and longevity, the SU-1017 is the obvious choice. Its base seal and sealing bead ensure a secure fit in the stock GSX-R air box and those multiple layers of cotton gauze have an estimated dirt holding capacity of over 70 grams. In the same K&N testing that garnered that impressive statistic, the SU-1017 showed an estimated overall filtration efficiency of over 98%.

Of course, the SU-1017R is a different story as its design goal is heavily weighted toward the performance end of the spectrum. The two layers of filter media will perform to the protection standards expected on the racetrack, but it is not designed for the real world.

The SU-1017 and SU-1017R for the 2017 GSX-R1000 come pre-oiled and ready to install

The K&N GSX-R filters are designed to install in the factory air box with a secure and reliable fit. No intake compartment modifications are needed. As stated before, the SU-1017R will require engine management modifications for its intended closed-course use.

Both the SU-1017 and SU-1017R come pre-oiled and ready to install straight out of the box. When the time comes to clean the filters, both models are fully washable and rechargeable using a K&N kit like the 99-5000.

The SU-1017 comes with a 10-Year/Million Mile Limited Warranty so it is likely the last filter you will buy for your Gixxer. The SU-1017R is warranted against defective materials or workmanship for a period of 1 year from the date of purchase with no mileage limitation.

Want more power for your 2016-2017 CTS-V? Try out the K&N 63-3096 for an additional boost in power

When the National Hot Rod Association (NHRA) signaled that the Pro Stock class would move from carburetors to electronic fuel injection (and a flat, more stock like hood at the same time) the NHRA turned to K&N's Advanced Composite Division to develop not only an entirely new air intake system but fabricate it in carbon fiber. The almost three-foot long intake, which collects air from the lower front bumper of the car and ducts it back to the regulation throttle body, is used by all competitors in the Pro Stock class and has performed flawlessly through countless passes.

The K&N carbon fiber AirCharger intake kit adds an estimated 50+ HP to the 2016-2017 Cadillac CTS-V

The application of carbon fiber to the Cadillac CTS-V is highly appropriate, as the woven appearance of carbon fiber has become a design feature on supercars and high-end performance parts. It is both sophisticated as well as highly functional.

The CTS-V, the most powerful Cadillac ever produced, comes from the factory powered by a supercharged LT4 6.2L V8 outfitted with direct injection, continuous variable valve technology, and active fuel management. In true Cadillac form, the LT4 develops an impressive 640 horsepower and 630 lb-ft of torque. That’s enough to register a 0-60 time of 3.7 seconds and a 200 mile per hour top speed (on the test track, of course).

The powder-coated heat shield protects cool incoming air from engine-generated heat

The 63-3096 K&N AirCharger air intake system replaces the restrictive factory air filter and air intake housing on the 2016 and 2017 CTS-V. The fresh intake air first enters an oversized 7.5-inch carbon fiber topped RP-2960 K&N high-flow air filter sited within a powder-coated heat shield that installs into the original air box space and protects cool incoming air from high underhood temperatures.

The overized tapered conical K&N Air Filter is topped with a carbon fiber cap

The carbon fiber intake tube of a K&N AirCharger significantly reduces restriction to incoming air flow as well as calms turbulence as it moves into the engine’s throttle body for a guaranteed power gain. The intake tube has been manufactured to accommodate factory MAF sensor and crank case vent hose fittings.

Best of all, the K&N AirCharger intake system can be installed in your 2016-2017 Cadillac CTS-V with simple hand tools right in your garage or driveway on a Saturday morning. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to the 2016-2017 Cadillac CTS-V that come included in the package.
