The Harley-Davidson® Motor Company has produced motorcycles that people all over the world have enjoyed for over 100 years. In 1999 they released their first Twin Cam motor. This line of engines has some characteristics of the previous EVO motor, in that it is a high performance push rod V-twin motor sandwiched between two fly wheels. This engine has been fitted into Harley Softail, Touring, and Dyna models since its release and has proven to be a very successful powerplant.
K&N Custom Assembly for 1999-2012 Softails, and 1999-2007 Tourings and Dynas.

High performance engines like this need to breathe as much as possible. With K&N air filtration technology owners of 1999-2012 Softail models and 1999-2007 Touring and Dyna models can increase the performance of their hogs with K&N's new RK-3909-1 custom assembly. K&N's  revolutionary RK kits are designed to improve air flow without taking away from the classic stock look by utilizing the factory Harley top plate.

The RK-3909-1 has a custom backing plate that fits onto the stock throttle body or carburetor. This backing plate is made from powder coated billet aluminum and dyno-tuned to produce added performance. This assembly also comes with a tuned velocity stack to streamline airflow into the engine for better performance, and perhaps one of the nicest features of the assembly are the oil channels that are incorporated into the backing plate to direct oil from the breather bolts back into the motor - no more "leaving your mark all over America."

The RK-3909-1 comes equipped with a washable and reusable K&N air filter and the entire kit is covered under K&N's Million Mile Limited Warranty. The RK-3909-1 comes with everything you need to completely install and experience an instant performance gain creating simple bolt-on and go horsepower.  It has been dyno tested to produce an additional estimated 9.5 horsepower and 9.6 pound feet of torque to the wheel of a 2010 Harley Davidson Fat Boy with 96 cubic inch twin cam, and estimated 6 horsepower and 6.11 pound feet of torque to the wheel of a 2006 Harley Davidson Road King with 88 cubic inch twin cam.  See RK-3909-1 dyno charts for details.

The RK-3909-1 will fit the following Harley models:

2010 to 2016 Can-Am Spyders Get Performance with K&N Air Filter

Replacement Air Filter for 2010 to 2016 Can-Am Spyders
Replacement Air Filter for 2010-2016 Can-Am Spyder Models
Until 2008 there existed a nearly imperceptible niche between motorcycles and other four wheeled vehicles. For those seeking the open-air riding experience, yet not convinced on the merits of two wheels, along came a Spyder. And in slightly less than three years, the Can-Am Spyder roadster with its three-wheeled stance has become a global phenomenon.

The Can-Am Spyder offers the kind of superb stability and handling two wheels can't, yet with all the benefits of an in-the-elements, wind-in-your-face, riding experience. With its distinctive Y-architecture - two wheels in front, one in back - the Can-Am Spyder roadster is a one-of-a-kind way to experience the freedom of the open road.

The steadiness of the three-wheel design is an automotive-derived BOSCH-engineered vehicle stability system (VSS) that integrates anti-lock brakes, traction control and stability control, providing riders with an exhilarating riding experience and an unmatched level of control and peace of mind.

The Spyder isn't just about stability though; its 990 V-Twin engine has riders aptly covered in the power department, and transmission options give riders a choice between manual and semi-automatic.  Riders can now unleash even more performance from their 2010 through 2016 Spyder RT models by simply replacing the disposal OEM air filter with K&N's CM-9910 performance replacement air filter. It's one of the most straight forward and easy performance enhancements owners can perform. This precision engineered, drop-in panel motorcycle air filter simply fits into the existing factory air box.

High quality products and the right balance of airflow, filtration efficiency, dirt capacity, and reliability are what K&N has represented worldwide since 1969. The K&N CM-9910 replacement air filter provides excellent filtration while also reducing restriction to increase engine performance, horsepower and acceleration.

Like all K&N replacement air filters, the CM-9910 air filter is washable and reusable and has the capability to run up to 50,000 miles before servicing is required, depending on driving conditions. K&N also backs this filter with their industry-leading Million Mile Limited Warranty, making this the last filter owners will ever need for their Can-Am Spyder RT bikes.

K&N CM-9910 fits the following:

Replacement Air Filter for select 2006-14 Volvo 2.0L and 2.4L diesels.
Volvo is breaking the "big square family vehicle" mold with their sporty C30 three-door hatchback. Since its beginning the Volvo C30 has quickly become a favorite for car customizers the world over, with modified versions turning up at the Las Vegas SEMA show. Some have called the C30 as close to automotive art as this category gets.

The Volvo C30 has also been referred to as a "hot hatchback," and though it may not be as powerful as some other hot hatches on the market, it is one of the more sophisticated and refined models available.  Several Volvo C30 models come with a 2.0 liter or 2.4 liter diesel engine.  K&N designed an air filter for these engines that fits the 2006 through 2014 Volvo models listed below.  These Volvo owners can add performance and save money simply by replacing the disposable OEM air filter with a K&N 33-2976 replacement air filter. It's clearly one of the most straight forward and easy performance enhancements. This precision designed, drop-in air filter simply fits into your existing factory air box.

The 33-2976 replacement air filter is washable and reusable and has the capability to run up to 50,000 miles before servicing is required, depending on driving conditions.
