AEM Air Bypass Valve Part #20-403S Customer Reviews

Overall a good product which is very helpful. I believe its a lil pricy for the size but worth the buy. I recommend for everyone that has a cold air intake.

Having this is lifts a HUGE worry off my chest about sucking in water and trashing my engine. Great product easy to install only thing I see wrong is I noticed a slight change in power when accelerating but I am willing to deal with it because it will pay off in the long run while driving in wet conditions!

By relocating your air filter under your front bumper, you put your engine at risk. This is really cheap insurance agaist water getting into your engine. But, this thing is thin and cheaply made. It's a good thing it installs easliy because it will last you about a year before the engine heat and vibration rip it in half and you gt to put on a new one, just like I get to do every year. Don't bother with the instructions, I think they are in Chinese. Just look at one in a photo, cut your pipe and put it on. If you can tie your shoes, you can install this.

this aem bypass valve is a must have item for your hard earned investment. the install is easy and the directions are very detailed and easy to follow. why take a chance with hydro-lock, when this product protects against all elements. autoanything has the best price and fastest shipping on the net and i've done alot of shopping around. rest assured next time you're driving in the rain or snow that you are protected with the best, j. cox, oklahoma city,ok

This valve takes the worry from hydro lock in case the system is emerged in water. It is a must. Installation is a bit tricky. Therefore, I suggest dealer instillation. It performs as expected and there is no loss in power.
