This is a NEW AND IMPROVED MACHINED BILLET ALUMINUM 72mm THROTTLE BODY AND POLISHED 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 and plenum kit you will have a quicker throttle response and faster turbo spool up, not to mention it's Billet Machine finish and polished plenum 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!
Both items are made in the U.S.A. Plenum only comes in high polished finish, while the throttle body is a machined finish.
