Injen SP Series Cold Air Intake Reviews


Reviewed By Robert B (SALT LAKE CITY, UT) Reviewed for a 2013 Ford Focus —10/29/2015 9:17 PM

I've seen increases in gas mileage and speed, roughly 12hp on top of what I have on my 2013 Ford Focus se, it gives its nice, clean, mean growl.

Injen Hydro Shield

Reviewed By Benito G (Dallas, TX) Reviewed for a 2008 Ford Focus —6/20/2009 1:45 PM

I purchased the Hydro shield after putting on a cold air intake on my Ford Focus. Hydro-locking an engine using a CAI is a very debated subject and I wanted a little more piece of mind so I bought The Injen Hydro Shield. I won't be crossing any deep water but if I get caught in a heavy downpour I'll have more confidence with the Hydro shield installed.
