STM Throttle Body Shaft Seals for DSM/Evo/3S

STM Tuned Inc.

$24.95 
STM-TB-SEALS

Quantity: 



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.

Vehicle Fitment:
1991-1994 1G DSM
1995-1999 2G DSM
Evolution VIII-IX
1991-1999 3000GT & Stealth
* Does NOT fit 1990 DSM *

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

1G Notes:
These do not fit 1990 DSM. They have one side that uses a smaller seal.

2G Notes:
The OEM 2G throttle body gasket MD302262 has been discontinued, so we are unable to offer the full kit.

Amazing service and quality

I ordered a set of throttle body seals and o-rings. It was delivered by mistake to a wrong address. Reached out to the team at stmtuned and they immediately acknowledged and re-shipped it overnight. Thanks for the great customer service
