The picture above just simply demonstrates what the streets of Boston and the Metro Boston area looks like after 4 days of consecutive rain.
O my friends GSR Integ had a CAI on it and drove through similiar water and he heard the CAI actually sucking in the water and then his engine stalled out... when he started it back up he got tons of white smoke coming out his exhaust but everything seemed fine afterwards.... He's very lucky.
I'm not trying to scare noone but for me I couldn't go with a CAI if I wanted to... especially being as the SI is my daily driver.
