Injen Evolution Cold Air Intake Reviews


Good Stuff

Reviewed By Randall K (ASHLAND, IL) Reviewed for a 2008 Chevy Silverado —9/5/2017 6:49 AM

Had a brand "X" cold air intake. The Hump boot went bad. Cannot order individual parts from that company so went shopping. Purchased an Injen, installed, and immediately noticed an increase in fuel economy. A great product! Also, noticed a list of parts by individual part numbers for the Injen setup. Nice!

Injen Power-Flow Cold Air Intake System Reviews


Not Bad

Reviewed By Thomas G (GILLETTE, WY) Reviewed for a 2012 Nissan Frontier —7/4/2017 8:27 PM

Installation had some challenges such as removing the stock filter housing, reconnecting the crankcase breather tube, & connecting the intake tube to the filter housing. Otherwise, the instructions were very detailed & easy to follow. It is a nice looking unit & I like the fact it is a dry filter as I live on a dirt road & dust seems to really stick to the oiled filter I have on my car. I have only had the intake on for a few hours, but there is a noticeable increase in power & sound.
