CAI question
I just put in a new CAI that extends down into the wheel well ('91 CRX). Is there supposed to be a guard in by the wheel or is that area open all the way to the front bumper? I don't have anything there to keep the CAI filter from being exposed to elements coming from the wheel (like rain, snow, etc.)
89 CRX si, now with b16!

I don't think there is supposed to be a splashguard there. The resonator hole was only designed for the stock airbox to stick out maybe an inch or two, not half a foot or more, like a cai does. If you wanna protect your filter(and engine) from water, you could wrap the filter, or you could by a by-pass valve. Or just do what I do, take the whole cai piping out, and put the filter right on the throttle body, when it's raining out.

Yes, there is supposed to be a splash gaurd there... Mine is missing from being so low for so long... Which is why I took the bottom part of my intake off and have been running as a ram air... I did run my stock engine like that for a while, and it ran fine... So I dont think a little rain and dirt will hurt it... But I took it off just after I swapped my engine just to be on the safe side...

I would def. look into devising somethin to go there or getting a new splash guard, your best bet would actually be to build like a little air dam thing down there to hold air in there, not hard to do just use some plastic, i wouldnt want my filter to be exposed like that however to the elements.

Wouldn't the the plastic piece that fits in the wheel-well protect it from wet wheels? Mine does :dunno:
I went a step further with my CAI. I made use of the resonator to house the filter. I then fabricated a scoop and mounted it to the front of the resonator so that at highway speeds air is somewhat 'forced' into the intake system. I don't get the kind of pressure that you would from a forced induction system (turbo or SC), and it isn't enough to require re-tuning the ECU. The theory seems to work and only at speeds greater than 40mph; not alot of gain, but enough for me to notice the difference.
