Key Features
-
HI-RAM DESIGN — 7,000–8,500+ RPM PEAK POWER: Extended-length tuned runners and an oversized high-rise plenum maximize airflow at extreme RPM. Designed exclusively for EFI fuel systems with included fuel rails. Target applications: naturally aspirated big displacement, large single/twin turbo, and supercharged builds aiming for 800+ horsepower.
-
92MM THROTTLE BODY BORE: Accepts 92mm throttle bodies for massive airflow capacity. The enlarged bore minimizes restriction and maximizes volumetric efficiency at high RPM — critical for forced-induction and high-combination NA builds.
-
INCLUDES EFI FUEL RAILS: Comes complete with matching fuel rails for a true bolt-on installation. No need to source separate rail kits — everything you need is in the box.
-
RECTANGULAR PORT FIT: Precision-cast to match LS3/L92/L99/L76 rectangular port configurations — ensures a leak-free gasket seal with no porting or modifications required.
-
PREMIUM CAST ALUMINUM CONSTRUCTION: Every runner and plenum surface is precision cast from high-grade aluminum with a polished silver finish — anti-rust, anti-corrosion, high-temperature resistant. Dimensions: 23.96" (L) × 13.33" (W) × 12.03" (H).
Hood Clearance Warning
The HI-RAM design measures 12.03 inches in height — significantly taller than standard intake manifolds. A cowl hood, scoop, or aftermarket raised hood is required for installation. This manifold will not fit under factory stock hoods on Corvette, Camaro, or truck applications. Please verify hood clearance before purchasing.
