I am please with the part. My Honda Civic LX 07 is a lot more responsive to the gas, gives me the extra push when needed and it sounds just right. Good product so far.

Purchased this filter for my 2012 Honda Accord. Perfect fit! Substantially quicker on acceleration! Also ordered one for my Civic & CRV! Thanks!

Hey, you want to go? Go K&N. I have used K&N oil and air filters for years. I don't put a lot of millage on my 1996 Chevy Astro Van. I change oil and filter in the spring and fall. The used oil is still very clean, more gold than black. I use a good high millage oil and [brand] lube. The motor has 115,000 miles on it and has never been torn down deeper than the intake manifold gasket.The van is a mild custom with a performance chip and straight exhaust. I have a cold air filter on order and can't wait for it to get here. I have a lot of fun blowing the doors of the young guns souped Honda Civics. With the new filter it will be even faster. Because of the weight and rear gears, my tires don't spin off the line. The chip kicks in a split second after I floor it. My son has a Civic with an Audi engine and a cold air system and can't even come close. With my new system, I will be even faster. By the way kids, I'm 68, so the next time you see some old guy driving, don't assume he doesn't have a little surprise for you. lol Stick with K&N oil and air filters and use good oil and your car will thank you for it.
