This is a NEW AND IMPROVE "GN1Performance ALUMINUM 72mm THROTTLE BODY UPPER PLENUM" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. With this throttle body plenum kit you will have a quicker throttle response and faster turbo spool up, not to mention it's polished finish with custom engraved power 6 look really sharp.

This new generation plenum is taller and wider than the previous model, allowing more air to flow even more efficiently than before! Now your IAC wont have contact with your intake silicone hose at all, thanks to the added height.

This item is made in the U.S.A. Plenum only comes in high polished finish.
