S90 Billet Aluminum Throttle Body for Evo 4/5/6
The S90 direct bolt-on throttle body for Evo 4/5/6 is precision CNC machined from AL6061 T6 billet aluminum for increased durability. Available with a 70mm or 74mm bore size and includes a new gasket and mounting hardware.
Vehicle Fitment:
CN9A Evolution IV
CP9A Evolution V VI
More Info:
The throttle shaft and blade assembly are CNC machined from AL7075-T6 aluminum separately to increase horsepower and torque by optimizing airflow to the engine, with the addition of two high quality bearings for smoother and precision control.
Includes:
• Throttle Body
• Gasket
• Install Hardware
Install Notes:
• STM recommends a 3" coupler for the 70/74mm throttle bodies. The 3" coupler is just a bit loose on the 70mm, but a 2.75" is way too small. The 3" coupler is VERY tight on the 74mm, but it does fit. A 3.25" coupler on the 74mm is way too big. Shop for Couplers and Clamps
