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.

Bought the filter for my new car, a 2014 Honda Accord Coupe, V-6. I have put K&N air filters in all my cars since about 2001. I find they increase top end power and help throttle response at lower rpms, and they usually improve gas mileage as well. Thanks for your great products.

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