Install Notes:

1. Coupler will need trimming on both ends to fit. We recommend trimming in approx. 1/8" increments using a worm gear clamp as a guide and a fresh sharp blade. Please be careful and use caution when performing this task.

2. We highly recommend using masking tape on the inlet to prevent scratching till you have the coupler perfectly trimmed.

3. Install all fittings with a ptfe tape.

Application: Subaru WRX 2002-2007, STI 2004-2021 — verify fitment for your setup.

Manufacturer's Warranty — Torque Solution

Torque Solution states a Limited Lifetime Warranty on its manufactured billet aluminum and polyurethane parts — engine, transmission and differential mounts, shifter and suspension bushings, blow off valve adapters, exhaust hangers, flanges and fittings. Its electronic parts (Fast Response IAT sensors and PNP speed-density adapter harnesses) carry a 1-year warranty instead. Wear and consumable items — turbo blankets, intake gaskets, exhaust wrap and heat tape — are sold without a stated warranty term. Coverage applies to the original purchaser against manufacturing defects; check the individual product listing for the term that applies to that part.

Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Torque Solution. Contact us if you need help with a warranty claim.
