The Holley Modular Mid-Rise intake pairs the popular GM LS3/L92 rectangle-port Mid-Rise manifold with a purpose-built plenum adapter and a 95mm EFI plenum top. With a max overall height of just 10.44\", it's an excellent choice for street and street/strip builds with limited hood clearance, delivering a 1,500-6,500 RPM power band well suited to turbocharged or naturally aspirated combinations.

Recalibration of the ECU may be required with this intake manifold design when running the OE ECU. Holley EFI LS main harnesses use an LS1/2-style MAP sensor connector; the 558-416 adapter harness converts to LS3 MAP, which is recommended for this manifold. This manifold is modular, and the 300-231 plenum adapter accepts Holley's popular LS Hi-Ram plenum tops.
