Open Filter - Driving in Rain

[Tyler2386]

You'd have to drive it into river to make it suck up enough water to damage the motor. Had many open CAI's & CAI's with ram air setups...rain isn't an issue.

Rain IS an issue if it affects driveability of the car, which it did in my case. I'm not necessarily concerned about damaging my motor, but if it is driven with a wet air filter and the MAF gets wet the car will run horribly.

My VFE Supercharger Kit for my M3 - with a low to the ground intake, actually included a "Hydro Shield" over the intake. I put about 50,000 miles on that kit, and never had a single issue.

I just ordered the ProCharger kit for this car, and was actually wondering about putting something on the intake for that kit...

There should be a splash shield where the PC intake sits already on the car.

I have to agree here. If the filter is soaked it must affect the air going to the engine at least a little bit; defeating the purpose of a CAI to begin with.

It is like trying to breach through a wet dish towel (please do not waterboard yourself lol). It's a lot harder to breathe air through wet cloth than dry because the pores are filled with water.

I can't imagine a soaked filter is an ideal situation, even if it doesn't damage the engine per se. Maybe the air getting blow in from outside blows the water out of the filter? I don't know the exact physics to it, but I just cannot see a soaked filter as ideal

Never had an issue. If you're using a paper filter, sure. K&N, Airaid & other similar filters are oil coated...would prevent that from happening. I would all the engineers of all the aftermarket CAI's out there would have taken that into consideration.

I am running VMP's Gen II with Roush CAI.
