Just purchased this air intake and bolted it on to my 2013 Honda civic Si 4d.... Amazing! It took me just over an hour to install .. The instructions were very easy to follow with little or no tweaking. The second I started my car ... The tone of my motor was more aggressive and sounded great. Acceleration was much improved.. (Almost like a different car)....Great purchase for the average guy to bolt on. Amazing results.. Thanks K&N!

I always replace my stock filters with K&N filters for fuel mileage and to protect my engine. Now I need one for a 2013 Honda Civic with the 1.8 liter engine.

Absolutely love the performance intake from K&N on my 2012 Honda Civic SI! Sounds like a different car and I've saved on gas mileage as well!
