yeah, those damn L36's have it all built in, i think ZZP has a throttle body plug...i doubt yours is the same though G.
Well, i was right
L36 TB Coolant Plug
The Easy Performance coolant plugs works by blocking the coolant passage in your TB. This keeps the throttle body cooler which increases horsepower. The product Only works on the L36 motor
and will not work on the Fbody.
