Injen Hydro Shield Reviews


Reviewed By Jeff P (Lilburn, GA) Reviewed for a 1999 Toyota 4Runner —3/15/2011 11:22 AM

The hydroshield appears to be working as designed. I've had it in some heavy rains for the past couple weeks and the filter is bone dry. I added a K&N FIPK air intake and have had to clean and re-oil several times since purchasing the vehicle in '04, because the rain water would break down the oils on the filter and dirt/dust would accumulate more readily. Water would eventually force the oils (and moisture) into the throttle body and onto the MAF sensor. This should definitely help preserve my air filter and keep things clean for longer.

Additional filter

Have a different brand CAI--- their filter fell apart and they didn't want to cover it.... replaced with KN a couple years ago. Still in great shape-- bought a second one so I have one to switch to during cleaning time. Have them on all my vehicles.
