Injen Hydro Shield Reviews


Works good

Reviewed By Peter K (HYANNIS, MA) Reviewed for a 2016 Subaru WRX —2/8/2017 1:02 PM

Works good at stopping water. Even running it under faucet no water got through. It also helps keep bugs gravel and leaves from getting stuck in the filter.

Injen CAI Install Duramax diesel

Reviewed By Jerel P (MONROE, MI) Reviewed for a 2015 Chevy Silverado —11/20/2016 1:16 PM

Quality product, well made, not to hard of an installation, just made it a little hard on myself with the installation, puting way to much thought into what i had to do, the tools i needed, etc.., i made it a 2 hour install, instead of 45 min. to 1 hour The Injen CAI looks awesome under the hood compared to the smaller stock chevy cai that was removed, smoother cleaner larger air box, large air filter, engine sounds completely diiferent than before, YOU WANT SOME, COME GET SOME!!!
