Well to clarify just a tad.... we mean VERY heavy rain. Like an inch in 10mins heavy rain! :eek3:
This past summer has been just about the rainest season I've seen in PA since I've been living here (12years?). I have a CAI, I've gone through plenty of puddles and been in PLENTY of "heavy rain" situations. No problems.
Only time I ever got water in my engine was when I wasn't paying attention while hosing off my engine and just happened to have the highpressure pointed right at the sparkplugs for a good 15 seconds. Couple of cranks and letting it air out for 10mins and it was fine.
I was extremely worried about getting a CAI and having water get in, I'm glad I got it. I'm really not worried anymore. I see now the bypass valve is more hype than anything.
