Honestly I plan on sticking with the stock intake because it is factory cold air and I don't have to worry about driving through a puddle. I'd suggest you find out where that filter sits and see if you can put a release valve in just incase so you don't hydrolock your motor in a heavy rainstorm. See if Stillen makes one. Remember that you get what you pay for. Yeah it looks like just a pipe but there are certain flow characteristics that certain bends will give you. It all comes down to dyno testing, and I'm nearly 100% certain that xyzracing does not have a dyno.
