Features

  • Keep your engine breathing freely even when your intake is submerged in water with AEM's Air Bypass Valve
  • Exclusively designed to work with your AEM Cold Air Intake System - V1 systems only, does not work with the V2
  • When your intake's main filter becomes submerged, your Air Bypass Valve automatically takes over, shutting off induction from the wet filter and drawing air in through its external diaphragm
  • The Air Bypass Valve's foam filter shields against dust, rocks and other harmful material
  • For maximum durability, the Air Bypass Valve features a sonically welded, nylon-reinforced cage
  • Nasty chemicals and the elements are no match for the Air Bypass Valve's urethane flapper valves
  • 50 state street legal when used with your AEM Cold Air Intake Kit
  • On the majority of AEM Cold Air Intake Kits, the Air Bypass Valve installs right to the upper inlet pipe
  • Comes with the proper hose clamps for a painless mount
  • AEM backs your Air Bypass Valve with a 1-year warranty

Description

Your engine needs oxygen to keep the fire burning in its belly. While your AEM Cold Air Intake reaches down below the bumper to draw in the freshest air, it's at risk for sucking in something deadly to performance: water. Equip your aftermarket intake with an Air Bypass Valve for a surefire defense against hydro-lock.

When your intake becomes submerged, your Air Bypass Valve immediately springs into action. It closes off induction from your main filter and reroutes the air flow through its external diaphragm. Plus, the integrated foam filter traps dust and blocks debris from getting into your powerplant.

Built tough to withstand life inside your engine compartment, your Air Bypass Valve boasts a sonically welded, nylon reinforced cage. And, its urethane flapper valves are nearly impervious to the elements and harsh chemicals.

All Air Bypass Valves are 50 state street legal, and most mount easily to the upper inlet pipe. Backed by a 1-year warranty.

Notes

  • The AEM Air Bypass Valve is not compatible with the AEM V2 Cold Air Intake

If you have an AEM cold air intake, you have to have this too

"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."

"I had to look online to find what the bypass valve looked like after instillation. It was easy to install but I didn't use the instructions that much in the installation."

"I got my bypass valve and installed it very easy. I only wish they would make the pipe out of the same material as the intake. My old one cracked throwing the idle off because it was before the mass air flow sensor, thus allowing more air to come in, usually not a bad thing, but threw the idle off. Everthing else is good, just use metal instead of plastic."

"Definitely a must have for rainy weather. The instructions were sort of unclear where to cut the intake. Had to go the AEM's website find out exactly where to cut the intake."

great product

Posted on 05/10/2007 by Robert G. (Birmingham,AL)

"I have a lowered honda civic with a full cold air intake so my filter sits about 1.5 inches off the ground. when it rains here you have no choice but to drive through puddles that are at least that deep so the bypass valve prevents my engine from flooding. If you are installing a new intake system the installation of the bypass is just as easy as the gasket would be."

Easy install and worth saving your engine

"It took me 5 minutes to chop my intake in two with the sawz-all and file down the edges, and throw it back together. I live in SoCal and don't get a whole lot of rain, but when it does rain, or i go on a road trip, i would hate to have the possibility of wrecking my engine on my mind. Under $50 to give me peace of mind? SOLD"
