Our fabricated air horn is black powder coated mild steel and a huge 3 1/2" in diameter!! The internal volume of ours is 38% bigger then the stock air horn!!
Testers have reported more turbo sound, faster spool up, and more boost!! Independent dyno tests have shown an increase of 15 Hp!!
Some minor modification to the wiring loom may be needed to make it fit. If you plan on using this with our bridge you must let us know in advance. We have to clearance them both.
This will fit any air box and tube that will fit the oem stuff.
