Description:
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 leaky seals and when the seals were replaced, we picked up 20 whp and 20 ft pounds! Nasty boost leak! Sold as the pair of seals and OEM throttle body gaskets are available in the purchase menu.

Includes:
Pair of Throttle Body Shaft Seals
(Optional) OEM Mitsubishi Throttle Body Gaskets

Notes:
These do not fit 1990 DSM. They have one side that uses a smaller seal.
