Precision Turbo Polished Plenum Adapter - 70mm for 1986-1987 Buick Turbo Regal | (022-1011)
PTE 70MM Plenum Adapter
This upper plenum is manufactured from polished aluminum, then CNC machine finished in house. Our plenum has been specifically designed to help reduce, and in some cases, completely eliminate this potential lean condition. As an added bonus, the plenum has a higher internal volume over the stock plenum, which increases the volume of the intake manifold, ultimately allowing your turbocharged engine to support more horsepower.
This upper plenum adapter is a direct bolt-on replacement for all 1986-1987 Buick Turbo Regals, as well as the 1989 20th Anniversary Turbo Trans Am.
This unit is fully compatible with either a stock 58mm throttle body, a ported stock 62mm throttle body, or an Accufab 65mm or 70mm throttle body. It includes a new GM upper plenum to intake gasket, and new fastener hardware, for a true bolt-on installation.
In testing, we have seen 2 - 3 tenths improvement in 1/4 mile ET and increases of 2 - 3 MPH in the 1/4 mile.
