For: Subaru WRX 01-07/STI 01-21
The PSR brand is all about bringing you high quality parts without the high price tag commonly found with such a product. This Throttle Body Coupler is made from 4-Ply, high temperature resistant silicone and is the perfect way to replace your old worn-out coupler which is a common failure point on the EJ turbo motor. Included are two stainless steel worm gear clamps with a narrow band to allow more of a “pinch” to eliminate the possibility of boost leaks which can occur with some wider, t-bolt style clamps.
Suitable for all WRX, STI and Forester turbo EJ20/EJ25 motors with the metal intake manifold.
