AEM Air Bypass Valve

Price Paid:  $0.00

Summary:
First off, i think this bypassvalve is something good to have. Id rather spend 40$ now then thousands later replacing my engine. Sure, it may never actually be used to save my engine from water but its there just in case, like insurance. Also i dont understand why people are saying you lose power, Ive actually heard you can gain power at higher rpms, becasue if theres a large demand for air that your airfilter cant supply, it will create a vacum, the valve will open and allow more air to get sucked into the engine with less resistance. plus it doesnt look that bad.

Strengths:
could possibly save your engine, looks ok, easy to install, doesnt cause drop in power.

Weaknesses:
not metal, may never be needed

Price Paid:  $200.00 from no where

Summary:
i have a friend that wasted money on AEM's bypass filter (bpf) and we honestly DO NOT see a point to using one in the first place, UNLESS you race auto-cross or road courses where the climate is VERY wet. we live in WA and my AEM cold air intake equipped sti has never had a problem on either type track in the rain, even under extreme conditions.
and to the two geniuses with previous posts (you know who you are): if you submerge your intake in water you will get water in your intake and cylinders regardless of having the bypass valve or not. (it might not be as much water, but still.......) ADVICE: don't drive your car through water deep enough to penetrate the engine compartment!!! LOL
as far as the other brilliant post goes: if the bypass valve was installed between the MAP sensor and the throttle body and not between the MAP sensor and the main air filter, (not bpf), then your car WILL NOT run if there is ANY air leaks AFTER the map sensor. ADVICE: buy a rubber hose that's just big enough to fit over your intake piping and use screw type clamps. this will last for a very long time. to fix it in the meantime....... use duct tape!!! LOL

the only practical reason to have one of these would be for off-road racing with 4x4's as well as rally cars.

BUT! the best advice for everyone wanting to try their hand at import customization, racing, or show competition: buy a standard wrx and do a JDM engine/tranny swap. they possess superior parts and reliability. you couldn't ask for a better built drivetrain off the manufacturering line.
oh, and did i mention that any mitsubishi vehicle is a POS?!?!?!?!?!?! get a real honda killer!!! buy a scoobie!!!

Summary:
I own a 1996 mitsubishi eclipse rs and the front end has a small hole where you can see pretty much all of the filter. the other night i was driving in the rain and water i guess was splashing up in there somehow. so the filter got wet and at around 3k rpms in 3rd, the car bogged because the filter's pores were clogged from the water and not enough air was getting through. luckily i didnt totally fry the motor and i got home ok, but it works perfectly fine now. i have it rigged for now until i get the bypass valve, (i covered the hole up with duct tape), but i definatly think getting it is the safest thing to do for me in the event that this would happen again.

Strengths:
prevents hydro locking in the event that any good amount of water would get into your filter, it acts as a back up.

Weaknesses:
you might lose 1-2 percent in performance.
