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).
92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold

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.

NOTE: The EFI versions of the LS HI-Ram intake manifold and fuel rail are designed to accept Bosch Style EV-1 or Magneti Marelli Pico fuel injectors. OE LS fuel injectors may not fit properly in the Hi-Ram EFI intake manifold fuel rail assembly. There is a kit available separately for the LS7 Hi-Ram EFI to allow the use of stock LS7 fuel injectors, P/N 300-230.
