Injen Hydro Shield Reviews


Does Its Job

Reviewed By JONATHAN T (Deer Park, TX) Reviewed for a 2004 Acura RSX —3/27/2007 8:28 PM

I have a CAI and my filter is very low to the ground. I recommend the hydroshield for anyone with a CAI. Although it wont prevent hydrolock due to submerging the filter in water, it does repel water sprayed onto the filter.

Injen for 2002 RSX base

Reviewed By Fred M (Murrieta, CA) Reviewed for a 2002 Acura RSX —3/23/2016 9:20 PM

The aluminum chrome finish looks great. It feels that I do get more hp but wouldn't know unless dyno tested or on a timed track. I assume, do to the location where it is installed, the air flow does not get fed thoroughly that the sound could be stronger.
