LS4 Throttle Body Coupler

Make sure to select the correct coupler for your intake. We offer a straight and a 45° coupler. Verify what coupler you have before purchasing.

For example our ZZP 3" Cobalt Cold Air Intake uses the 45° coupler, and our ZZP 3" Redline CAI uses the straight coupler. Keep in mind that you will also need a LS4 throttle body adapter plate or you will need to port the inlet of your blower to clear the larger LS4 throttle plate.
