my advice: get a K&N filter and remove your resonator

some models of sri come with heat shields depending on the brand but i think you can buy them separately if I'm not mistaken

I just switched from a CAI to a SRI due to rain and there is a noticable decrease in power, no matter how slight, there's still a difference. But I dont have a heat shield, so who knows.

it rains alot but like it doesnt flood, does even the slightest chance of a bit of water getting into the intake mean bad news?
you need to completely submerge the filter under water to hydro-lock your engine. so if its just regular rain than you shouldn't be worried...that much, but once you hit a deep puddle when its pouring outside than best of luck to you. best possible solutions is get a by-pass valve (AEM makes cai with these), stick to a sri, or get an ice box intake.

No, you don't.

Say you have a 2.0-liter engine (just because it makes for simple math). Each cylinder measures 500cc. If one cylinder sucks up 100cc of water then you're in trouble. If the engine has 10.0:1 compression ratio (GSR C/R and easy math purposes), then combustion chamber would be reduced to 55.5cc at TDC. So a piston going up with 100cc of water in it is on it's way to self destruction. Water does NOT compress. When the piston reduces the combustion chamber to 100cc, the piston WILL stop. And if you are lucky, you're engine will too. If it doesn't then blown headgasket, broken ring lands, broken rod or any combination is likely.

Just a thought. Consider 60cc of water will have the same effect. 60cc of water is only 2 shot glasses worth of fluid.

A bypass valve will prevent this. As long as you don't go flooring it with the filter under water
