Key Features
Recalibration of the ECU may be required when using this intake manifold design with OE ECU. 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
The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a purpose built plenum base adapter and a Holley 95MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44", the Mid-Rise manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance. It's perfect for turbocharged, or normally aspirated applications. | This manifold is modular, and the plenum adapter (PN 300-267) will accept all of the popular Holley LS Hi-Ram plenum tops as a foundation for custom induction systems. | *** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions.
