Glen swears by the ARB snorkels. I spoke to a Sami owner at the Dixie Run (Tellico) last year that had a homemade snorkel, no airbox w/ K&N instet on top of it, and he swore by it. I also ran into a lowrider Kick in Cookeville that had a Acura Integra aftermarket tube in place of her Box (chrome 3 1/2 tube w/ K&N slip on filter, like on most built street racers) She also swore that it was a great improvement.
