Precision 70mm Upper Plenum, Cast
Product ID: P-022-1010

Details 

This new design was developed to address the severe airflow distribution issue with the factory upper plenum. The factory upper plenum, although good for its time, has an inherent design flaw that allows significantly more airflow to the back two cylinders which can create a lean condition when increasing the power on these vehicles.

Includes a new GM upper plenum to intake gasket, and new fastener hardware, for a true bolt-on installation.

Price: $149.99

With a satin black anodized, 6061 aluminum billet wastegate cap you will have years of good looks and protection from the elements.
