Injen SP Series Cold Air Intake Reviews

I Just love the shiny looks and the performance. Very easy to install. I was a K&N fan for many years until the Injen Cold Air Intake came along. It's half the price of K&N and the air filter requires no oiling or spraying to foul up your MAFC. You just vacuum it out! I did buy an aftermarket heat shield because it didn't come with one. It's the best on the market for HP and Torque! Love It!

Nano filters are the way to go

Reviewed By Mark K (Topeka, KS) Reviewed for a 2015 Honda Civic —2/11/2018 8:34 PM

Been using Injen dry filter for long time. Aside from AEM..this is my preference filter. Keeps dirt out of engine and my oil changes show less wear in analysis. Add the nylon pre filter too for xtra filtering. Using this filter on HPS SRI.
