Remove your dull OEM top mount intercooler coupler and replace it with a PERRIN coupler kit and give your engine bay a touch of style.

Silicone Couplers

The PERRIN Performance intercooler coupler kit replaces your factory coupler with our high-gloss, vibrant color hose that looks and works better. Our silicone couplers are made from fiber reinforced 3-ply silicone tube. Our high strength reinforced silicone's multi-layer design is capable of withstanding extremely high pressures and temperatures.

T-bolt Clamps

For maximum holding power look to the genuine PERRIN Performance Stainless Steel T-bolt clamps. Our clamps are guaranteed not to damage the expensive silicone couplers. Each is laser etched with the PERRIN logo.
