AEM CAI, driving in the rain today, through the puddles on Florida ave, not a problem. Cold air intake for a year and a half and no hydrolocking
Are you running the stock engine? How deep was the puddle, and how high is your intake(you generally need a good 12'' puddle before water is getting to the fiter with most CAIs)? How do you know your intake sucked up water (your filter being wet doesn't mean anything other than your filter is wet)? Did you take out your plugs and observe water/spray water out while cranking? Did you consider that maybe you bought an engine that was on its way out in the first place?
Just gathering info for future CAI vs Short ram threads
