    I recently installed a cold air intake system on my 2003 Honda Civic and took a road trip from Indiana to Washington, D.C. with a buddy. I normally get 33 mpg on the freeway before the installation. I weigh 315 and my buddy 205. We drove 75 mph with the AC on got 38.89 mpg!! Your air intake system is the BEST. I have purchased ones for my other vehicles. Keep up the good work.

    Purchased a new K&N replacement filter for my 2013 Ram 1500 quad cab. I've used them in my 2007 Nissan Titan, 2006 Toyota Solara, 2001 Lincoln Continental and my 1999 Honda civic. It's a top quality, must have product. It possibly saves a few MPG's per tank and each vehicle seems to breathe better. It also saves money buy purchasing an $11 recharge kit rather than buying a new air filter every few thousand miles and it's backed by the best warranty in the industry. I am 100% pleased and will continue to purchase this item for every vehicle I acquire in the future.

    Actually got 5 hp and 7 ft lbs torque jump with this easy to install air filter, Also got 4 more mpg with this. What a great deal. Save money and more power. I would reccomend this part to all my automotive enthusiasts friends. I also use the K&N 10 10 oil filter for complete engine protection. We have an 08 si with a type 69 cold air tube and a crv that uses K&N parts and finished a s2000 honda sports car . We use all K&N filters and cold air tubes on every honda applicable.
