idk what this does...
I took mine of a while back its supposed to give you a little more turbo whistle is what they say. Some say quicker spool up. Its real easy just plug the hole in the intake with a 2 1/2 quick plug i got one from home depot.
I would say i maybe got some more whistle, but for $3 its worth a try.
