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.
Features:
- Provides great performance to 6500 rpm for street/strip performance applications while providing the look of a racing EFI intake manifold
- Unique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power
- Great for supercharged or turbocharged engines
- Power band from 1500-6500 rpm
- May require an aftermarket hood for some vehicle applications.
- Cast aluminum construction
- Intended for use on all GM LS Gen III or IV engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with OE ECU).
- Black Ceramic Coating for an aggresive look in your engine compartment
