Green Air Filters Reviews

Easy BOV sound alternative

Reviewed By Matthew L (Oxnard, CA) Reviewed for a 2013 Ford Focus —3/12/2015 9:29 PM

The boost-dump sound is why most people will be picking this over a K&N or similar filter, so I'll say its definitely a good sound. I was worried about it being too loud and ricey, competing with my Borla Exhaust for attention, but it doesn't. That said, the induction sound is also louder, so if you're not a fan of louder whistling on acceleration, this may not be a good call. That boost-vent though...

K&N Air Filters Reviews

Good value

Reviewed By Joshua S (Apple Valley, CA) Reviewed for a 2013 Ford Focus —1/26/2015 8:10 PM

Another quality product. Installation took awhile as the filter didn't want to slide into the Airbox without a fight and the Lid needed trimming. Would buy again. I use these filters in all my vehicles.

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.
