When I get a CAI will I need to take it off when winter comes and there is a foot of snow on the ground again?

I'm trying to make some decisions on performance mods here before long.

All of the CAI designs currently available all locate the filter it a "protected" area. The KORE, MHP, Tunez Special and Random Special, locate the filter in the fenderwell. A small ammount of snow may work it's way into the fenderwell, but it will pose no performance problem. 12" of snow = 1 inch of water. So assuming snow packed into your fenderwell, all melting at once, your filter would get wet...then that water would have to travel 3 feet up, past various kinks and bends...then make it past a hot intake manifold and head...past hot valves...and into your engine compartment.

In other words...I would not worry about it too much.

I'm not 100% sure where the Speedstate/AOS design put the filter, but I BELIEVE it puts it at the bottom of the engine near the lower engine shield...so it too would be protected.

Cool thanks random, do you think since we do get quite a bit of snow in IL at some times that it might be a wise idea to get an AEM bypass, just to be safe?

Random

The AEM bypass is just a piece of insurance. 99% of the time you will never need it, but the piece of mind you get from having it is worth the $50.

The AEM bypass doesn't offer any sort of performance hinderance does it?

The AEM Reps say you lose 1hp, but that's no biggie.

I've also heard that the bypass only works theoretically, and it's not guaranteed to keep water out.

So if this is the case, what would be the point in getting one if it costs performance, and chances of the intake actually sucking up a lot of water are slim?

I think this is my last question on the CAI subject, I have no foglights, and I'm not for sure where the end of the CAI actually comes to rest at, but could it suck in rain water from lets say a vehicle in front of me if it were raining pretty heavily?

Your filter will reside in your fenderwell behind the stock fog light by about a foot. There are water drain holes there to prevent water from "pooling" there and your filter sucking that water up.

The AEM Bypass is an "insurance" item. Some people (not on our forums) have hydrolocked their engines. The AEM Bypass will prevent that.

It is really a small price to pay for the added piece of mind it will give you.

So in my case, would not having foglights make me more prone to have hydrolock?
