Mid-Rise Plenum Base Adapter Kit - GM LS1/LS2/LS6 - Black
Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum adapter (PN 300-267BK) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.

- 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).
