My tube made 5 hp more with the K&N filter than a standard legth tube with the same filter, and up to 10 hp more with extra fuel and ignition tuning. Certainly bang for the buck.
Unfortunately, finding the proper length and diameter for your car is an expensive endeavor, unless someone else has already done the legwork for you.
