got the skunk2 on couple months ago. I drove up to canada last thanksgiving in a huge downpour, i have a CAI. When I got into vancouver my car started making this loud *** noise, but only at low RPMS. the next day it was brightr and sunny and no more noise. Time passed and it made the noise everytime it rained. Just lately its been getting REAL loud and is actually vibrasting the car.

At first I thought it was an exhaust leak, but then why would it only do it when it rains? my only other idea would be that my CAI is sucking in water.

Any ideas?

 

hmm.. is your CAI protected?

 

i would think it's virtually impossible for water to be sucked up an intake pipe unless it's completely submerged in it..

maybe water is getting into the exhaust through the tailpipe affecting the sound reducing properties of the muffler..
