Had to remove my induction kit this year.
Heavy rain driving to and back from Poland, engine went "limp mode" due to the MAF getting "erogenous" (oops...typo) signals.
Really, REALLY wet driving.
Moisture sucked straight in.
Came home and put the std filter back (after having to move a handful of relays and wiring, then went into the extra space.)
Thinking about having to drive some 4000kms with an engine that shut down every time it p*ssed it down, convinced me to go back to std.
