2003-2006 Mitsubishi Evo 8/9, 1991-1999 Mitsubishi 3000GT, and 1991-1999 Mitsubishi Eclipse GST/GSX High Pressure Throttle Body Shaft Seals by STM
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!

Performed a smoke test on my Evo an found the throttle body seals leaking. Replaced them with these at back to 39psi of boost! Highly recommended.
Fixed a common boost leak on these old cars. Replaced oem ones at 160k miles. Easy install would recommend ordering a couple incase you accidentally mess up when pressing them into the throttle body.
Perfect fitment. Shipping was super quick.
Fixed my long standing boost leak at the throttle.
Thank you guys for the prompt delivery. I ordered these twice only because they are very delicate. The first delivery was next day and it literally was that, less than 24 hours later I had my part.
Fixed leaky throttle body as advertised.
