Product Reviews Review part RK-3930

Just put the kit (RK-3930) on my 2010 Electra Glide (flhtc) Harley motorcycle. It was very easy, faster throttle response and was pleased that the idle stayed the same. I have other K&N kits on other motorcycles and never had been disappointed of the functions of the kits. Thank you all for doing such a great job on the manufacturing of K&N. Blessings

Coming from Southern Calif. as I do I have been a big fan of K&N air filters for a long time and today was no exception. I just finished installing the RK-3909 air cleaner/filter kit and I must say I was not only impressed with the hardware and the way everything went together and fit perfect but the step by step instructions (with photos) were great. You see writing instructions is something I know a little about as a retired aerospace Mfg. Engineer I wrote instructions for the guys making the parts as well as putting together of rockets and all types of aircraft.

Well done and thank you,

My 2008 Colorado Crew Cab was great - until you had to put your foot in it and pass someone. I had always heard good things about K&N and the benefits to horsepower and acceleration. The filter to fit my vehicle's 3.7 liter engine had not even been released yet, but I told my local dealer to order it as soon as it was available. The difference in performance was immediate. The acceleration is now everything that it should be, and is completely responsive to what I need it to do. I have become an advocate for K&N and recommend them anytime I get the chance. A friend didn't hesitate in taking my advice when it came to upgrading his new Harley Davidson Dyna Glide! Kudos on a job well done!!!
