Product Description

The PERRIN PSP-ITR-321RD TMIC Coupler Kit is a direct replacement for the factory throttle body coupler on select turbocharged Subaru models equipped with a top-mount intercooler. Manufactured from reinforced 5-ply silicone, it offers substantially greater resistance to heat, oil, and boost pressure than the OEM rubber hose while providing long-term durability and improved reliability.

Finished in a vibrant red color, this coupler enhances engine bay appearance while maintaining a secure, leak-free connection between the intercooler and throttle body. The included stainless steel PERRIN T-bolt clamps provide even clamping force for dependable sealing under high boost conditions. Designed as a direct bolt-on upgrade, the kit installs without permanent modifications and is ideal for both stock and modified Subaru turbo applications.
