Celica Forums General Discussion Exterior bypass valve AEM

Ok well, i have an AEM CAI, and i need to get a bypass valve for it, but im unsure what size it is, also, will the bypass valve decrease HP in any way, this is the one I have

Dont get it...it does not work for our cars. Also, it has a volentary recall out on it. A piece can break off, and lodge in your throttle body.

As long as you dont drive through a river, you wont hydrolock. The filer has to be totally submerged to hydrolock.

well the plastic for my wheel well is gone, so the filter is totally exposed..should i just get a shield..will the injen shield work well??

I thought there was an install here..but cant find it now. Just take a sign (like a garage sale sign), paint it black, then cover up the whole in the wheel well (rivits or screws).

--EDIT--
I found the install.

you need to clean your engine bay, pronto!

I agree...I just about cried when I saw the mess...especially the paint chips!

wooohhhhh...clean it already

thats an old pic, here it is now

and here is my filter...i know its bad

2.75" AEM Bypass Valve (20-402s)

AEM's Air Bypass valve for Cold Air Induction Systems virtually eliminates the unlikely chance of water ingestion should the filter element become wet from deep puddles, rain, hail, sleet or snow-or any other scenario in which the filter element could encounter or become submerged in water. The valve installs along the upper portion of the inlet pipe on the same axis as the throttle body centerline. Should a drop in pressure occur within the pipe due to filter submersion, the valve shuts down induction at the filter and routes incoming air through its external orifices, eliminating any chance of water ingestion.

The AEM Bypass Valve is used to protect the engine from hydro locking. Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle becomes submerged enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition. The distance of the filter from the road dictates the level of water that can cause damage. This distance varies with the vehicle ride height which is why there are no published numbers for this measurement.

The bypass valve may cause a slight loss in power due to the interrupted wall section created by the internal shape of the valve. In dyno testing we have found that the power loss is minimal. The bypass valve offers great security against hydro locking the engine in rainy conditions. If maximum power is the requirement, we suggest that the bypass valve be used in the rainy season and when racing use a coupler hose to make a smooth section where the bypass valve goes.

AEM's Air Bypass Valve is for use on AEM 2nd Gen Cold Air Systems only and cannot work with 1st Gen AEM Intake because of the way the 1st Gen is bent/setup.

Installation for AEM Bypass Valve on AEM 2nd Gen Cold Air Intake
By slik_gts

The install is pretty simple.
Don't use a hacksaw to cut the pipe, Take it to a nearby muffler shop and asked them to cut it w/ a power tool, takes only 2 secs for them to split the pipe (and is usually done for no charge).

You want to make sure that you cut out the piece marked by the paper template that comes with the bypass valve, otherwise the pipe will not fit correctly.

Install very simple and probably the best thing you can do to protect your engine from water ingestion. (injen splash guard can also be purchased to go around your filter for much more protection)

KULOD, the next best thing for you to do to compliment how detailed your engine bay is...

Polished Aluminum Heat shield/Splash guard used on Cold air Intakes to help avoid excess water ingestion or on Ram air Intakes to avoid heat soak!

By deflecting hot engine compartment air, a heat shield helps cool the Intake air charge and boost power. This is a great addition to your air induction system, and a perfect accent to detail your engine bay.

Features polished aluminum construction and etched Injen logo. Fits most aftermarket air filters with 2.5, 2.75, and 3 inch outlet flange such as INJEN, AEM, AC, K&N...etc.

I agree, the heat shield looks cool...especially on the short ram Intakes.

will the heat shield fit in where my filter is?

yep

thats why its called "heat shield / splash guard" (ie; thats what it is for... )
