Harley Davidson motorcycles carry a specific exhaust note that can be recognized from a mile away. When a group of them hogs ride together, the earth literally shakes as they pass by. There is nothing quite like an American V-twin rumble. Another bonus about Harleys is the endless aftermarket products available. It gives riders the opportunity to customize their bike however they see fit. Personality definitely takes shape when building your own Harley. Some like chrome, others like black. Some like old, some like new. Some like white walls, some don't. The list is endless.

One company that many Harley riders relate to and trust is K&N air filters. Many riders have used K&N products on their bikes for the last four decades. The performance, reliability, and reusability of a K&N air filter allow riders to ensure their bike is getting maximum protection for many miles down the road.

If you check out your neighbors Harley you may notice that their Road King is spotless. That is because most Harley owners are meticulous when it comes to their bikes. The people at K&N feel the same way. Dirt does not belong in or on your Harley Davidson. Protection is crucial.

Also important is performance. That is why K&N recently designed this aftermarket air intake system that can really wake up that powerful V-twin engine. K&N's Street MetalTM line of air intakes include part RK-3933, also known as the "Hammer" design. It is constructed around K&N's HD-0800 replacement air filter and includes a custom backing plate, billet air filter cover, and the hardware needed for installation. This open element style air intake greatly reduces air restriction.

K&N dyno tested a 2010 Fat Bob with the 96 cubic inch motor while equipped with the RK-3933 air intake. Test results showed an estimated gain of 10.1 horsepower and 10.2 lb-ft of torque to the rear wheel at 5204 rpm. This is quite a substantial gain for any vehicle on the road. Testing on a 2006 Harley Davidson Road King with 88 cubic inch motor revealed an estimated 7 horsepower at 5204 rpm.

You can most certainly trust that RK-3933 is made from high quality parts, because K&N backs it with their Million Mile Limited Warranty. So if you are looking for a little more power and increased throttle response, check to see if RK-3933 is listed for your Harley Twin Cam motorcycle below:
