STM Throttle Body Shaft Seals for DSM/Evo/3S Add Throttle Body Gasket:Add 91-94 1G DSM Gaskets Available with 3 finish optionsWhen 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.
