This silicone coupler kit includes two couplers, one for each side of the motor.

Diameter at the turbocharger inlet side is increased to 2.75" to allow for compatibility with the often used Garrett PowerMax turbocharger upgrade. Silicone is 5-ply reinforced black silicone with white COBB logos. Two new clamps are included to be used on the turbocharger side of the inlet coupler.

Why?

If you have a set of COBB Redline Turbo Inlets for your Gen3 Ford Raptor or 3.5L F-150, these couplers make upgrading to the Garrett PowerMax turbos a bolt-on affair.
