Ditto to what everyone has said. I have a a single tube, Needswings style cold air setup which has the filter in front of the radiator. If I had to do it again I'd go for the SL55 setup and here is why. I live in So. California so it doesn't rain much but it can really pour when it does. I worry about all that rain getting sucked into the engine and ending up with hydro lock. I wouldn't worry about the SL55 setup. It costs a whole lot more than $168.00 and takes a little work to adapt it but it flows well and it flows cold and the big air boxes look pretty nice.
