Evolution VIII-IX
1991-1999 3000GT & Stealth

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.

Perfect

Finally got the item in hand today 7/7/21 despite it being over 2 weeks after delivery, pandemic situation has customs process in a terrible state. Anyway, I’m using this on the CM5A chassis, 4g93t GSR throttle body in case anyone needs confirmation. Has not been my first purchase and surely won’t be the last 👍🏻

Too tight and now they're destroyed

These were so tight on my evo 8 they were destroyed trying to install them. I cleaned the opening lubed the opening and the seal, used a 10mm socked to drive the seal into the hole with the rubber side down and they're too tight. I'm going to try regular TB seals because these are made too big.
