Injen SP Series Cold Air Intake Reviews

I bought it for the sound it makes.

Reviewed By Daniel T (FAIRFIELD, OH) Reviewed for a 2008 BMW 1-Series —4/15/2015 3:16 AM

My BMW was way to quiet for my taste. I wanted to have a car sound like a machine it is. In the higher RPMs, it roars and I like that. I sure there was a performance gain, but I never put it on a Dyno.

Great price and value, prevents my engine from getting water in it. Good look and tight fit. Easy install as well.

Nano filters are the way to go

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.
