STM THROTTLE BODY SHAFT SEALS | EVO VIII-IX | 91-99 DSM | 91-99 3000GT


STM Throttle Shaft Seals. Sold as a pair.

When these seals wear out, they can cause leaks, sticking, and jamming of the throttle plate.
We tested a car on our dyno at STM with OEM leaky seals...
When the seals were replaced, we picked up 20 whp and 20 ft pounds! Incredible Boost Leak!

Fits:
Evo VIII-IX
91-99 Turbo 3000GT / Stealth
91-99 Turbo DSM.
**These do not fit 90 DSM: they have one side that uses a smaller seal.

OEM throttle body gaskets are available in the drop down.
