Aem Bypass

[BlackJack]

I remembered reading awhile back about people being concerned with water intake in the CAI setup being low in the left fender. I'm sure everyone knows about it already, but for those that dont know, AEM makes a bypass that mounts high on the intake piping and if the lower intake starts sucking up water, it reroutes air flow from the bypass high under the hood. Price is about 50 bucks, seen em new in the box for as low as 30 on ebay. Sounds like a decent insurance install. Any comments on this?

yeah, ive made mention of bypass valves several times when the water issue comes up, but don't think anyone has ever tried it.

They talk about it all the time on the elantra forum I belong to.

well, I have heard from several sources that there doesn't seem to be any noteable power reduction when it's activated, and definitely when it is passive, so I think it's likely to be a worthwhile investment, so I'm going for it, and I'll let you know how well it works out.

I'd recommend spending $50 for cheap insurance than a couple grand for a new short block!

ya ive got it on my stage 3 intake..i got it for about 34$....I would highly recommend it to anyone.....

I personally haven't used one, but I have heard some things about it. First off, they had a problem with the filter element getting sucked into the motor. Second off, these will do absolutely nothing unless your cone filter is totally submerged in water. Your intake will still suck in some water when you are driving in the rain, whether you have the bypass or not. To me, this is a waste of money. I never had a problem with my CAI, and I live in Florida. I've driven the car in many storms, including hurricane Ivan, and it never hurt the motor.

I just switch the intake back to WAI when I'm not racing :thumb:

^^^That's just about the safest method you are going to find.

And if your intake cone filter is totally submerged you are most likely going to have much bigger problems than just the intake.

^^^True!

yeah as was said b4,

this thing is a waste of cash IMO

cuz ur still gonna get water in there from rain, and splashed water,

How many times has ur car been submerged in water halfway up the bumper?

I'd suggest u buy a k&n cone filter, it will hold back normal water better than a cheap autozone cone
