Performance Design pTR Intake Manifold LT1/L83/L86
PERFORMANCE DESIGN
The plenum is constructed from molded nylon for a reduced cost alternative to the popular Carbon pTR. The same polymer lower runner pack resists heat soak from the heads and houses all ports/sensors hidden in the valley. The combination of materials offers a 10 lb weight savings over competitive aluminum tunnel ram manifolds.
Add port injection to supplement or replace the Gen V LT’s direct injection with optional billet -8AN fuel rails.
