K&N Air Filters Reviews

2009 focus

Reviewed By wesley h (QUARTZSITE, AZ) Reviewed for a 2009 Ford Focus —5/10/2013 6:59 AM

We seem to have picked up about three miles per gallon-hard to judge any power increase as the focus is really snappy to start with. Very pleased with the K & N filter.

Green Filter Rocks!

Reviewed By Ardis D (SCHERTZ, TX) Reviewed for a 2015 Ford Focus —9/23/2015 2:42 AM

One of the best bang for your buck performance mods that you can make. Picked up a few HP and gas mileage went up. Also intake sounds a lot more aggressive.

Injen Hydro Shield Reviews

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.
