Product Description

The PERRIN PSP-ITR-321BK TMIC Throttle Body Coupler Kit is a direct replacement for the factory rubber intercooler hose found on select turbocharged Subaru models equipped with a top-mount intercooler. Manufactured from reinforced 5-ply silicone, it provides superior resistance to boost pressure, engine heat, and oil exposure while reducing the likelihood of cracking or boost leaks commonly associated with aging OEM rubber couplers.

Finished in black for a subtle OEM-plus appearance, the coupler includes premium stainless steel PERRIN T-bolt clamps that provide consistent clamping force without damaging the silicone. Designed for easy bolt-on installation, this kit improves durability and reliability for both stock and modified vehicles while maintaining a secure seal between the intercooler and throttle body.
