    Holley 300-140 Details

    The new Holley EFI Hi-Ram intake provides the ultimate performance with the new GM direct injected Gen V 6.2L LT1 engine.

Each runner has a large radius where it meets the plenum, and optimized taper And cross-sectional area to perform in a wide variety of engine configurations.
