We price match!

This Torque Solution turbo inlet hose fits 02-07 WRX and 04+ STi with a 3.3" (84mm) inlet turbo. The silicone inlet hose is much larger in size than factory and smooths the air entering the turbo compared to the restrictive OEM corrugated inlet hose. Made from 4-ply high grade silicone and wire reinforced to prevent collapsing under high pressure. Includes a black anodized billet aluminum joiner to connect to a 3" intake.

Important Note:
The Torque Solution inlet bypasses the PCV Diagnosis Port. You will need to perform a simple bypass.
  1. Locate PCV Diagnosis connector (grey or white depending on year), which located on the block next to throttle body.
  2. You will need to use a pair of needle nose pliers to remove the jumper pin inside the PCV Diagnosis connector. This pin should pull out easily only using slight pressure. Do not discard the jumper pin removed from the connector.
  3. Place the jumper pin into the female harness plug that was connected to PCV diagnosis connector. Use electrical tape to secure in place.
  4. The open port will either be fed into the inlet by using the supplied T fitting and hose by keeping the PCV in place connecting to 1 of the front inlet ports or by connecting to your AOS/Catch can setup by removing the PCV.
