I am very happy with this purchase. Have 2 other cars with K&N's installed and wouldn't have it any other way. Pay a little more up front but the savings in fuel and replacement costs are worth it. They are a breeze to clean and re-oil. Buy one.. You won't regret it!

Installed on 2007 Civic Si Sedan. Easy install, 5 min tops. Car used to purrr at V-TEC kick, now it growls. The OEM filter (brick) was choking my car! Long time K&N user and always more than satisfied with their products. Best $40.00 you can spend on your car.

I own a 2008 Honda Civic SI Coupe and wanted to get a Cold Air Performance Filter, but, they don't make one for my car that is smog legal. So, I purchased this one in hopes that it would help my car perform a bit better, and it did! The engine sounds a little deeper and it responds better. I am very happy with the K&N Replacement Air Filter and it was a great price!!!
