Mid-Rise Plenum Base Adapter Kit - GM LS1/LS2/LS6 - Black

For use with LS Dual Plane Mid-Rise intake manifold base to adapt to modular tops.

NOTES: Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.

  • Provides great performance to 6500 rpm for street/strip performance applications while providing the look of a racing EFI intake manifold
