STM High Pressure Throttle Body Shaft Seals
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!

- No throttle body boost leaks!
