AEM Air Bypass Valve - New
Part 20-402S (2.75")
$35 shipped OBO

AEM’s patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your AEM Cold Air induction system becomes submerged in water. On most systems, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in.
Installation instructions included.

would it fit on an injen intake?

 

its probably would, depending on le diameter. I also have a bypass valve and I think the inner diamerer is 2.5

 

this should fit most intakes, from personal experience i have used this on 3 different intakes and has worked well....definitely a good part for those running cold air intakes.....

bump for a good and important peice...

 

It would if the diameter matches. I couldn't find the spec on the Injen though so you might want to break out the ruler to double check.

 

great deal. these little fkers are expensive normally
