Are u looking to get maximum performance out of your new direct injection GM LT1 power plant? Holley’s new Hi-Ram EFI intake provides the ultimate performance gains for your 6.2L (LT1) and GEN V 5.3L engine. Holley engineers designed the LT1 hi-ram intake with a modular 2 piece design, allowing for easy disassembly when you’re swapping out multiple tops, doing port work or designing a custom induction system. An O-ring seal at the plenum makes short work of swapping out tops. Dovetail shaped grooves help capture the cylinder head port o-rings making the installation, headache and leak free. Provisions for a MAP sensor and 3 Vacuum Ports are machined into the back of the intake. If you’re looking for induction options Holley has them. We offer 5 unique plenum tops including a single 95mm or, single 105mm throttle body design. Or you can go old school and mount a pair of 4150 or 4500 series carbs on top of that LT1. But if you want to get real creative choose our blank flange and create your own unique induction set-up. The engine is feed through tapered runners with large flowing radiuses for a smooth transition from the plenum to each cylinder. The large volume plenum and optimized cross-sectional area makes Holley’s Hi-Ram the perfect choice for a wide variety of engine configurations with a power band from 3500-8000+ RPM. And if you just can’t get enough horsepower and want to increase the performance potential of your LT1. Holley also offers an intake with injector bosses cast into the intake runners. This allows you to add more injectors in addition to the factory direct injection. Holley intakes w/ Injector ports include anodized, laser etched fuel rails with a dual pattern injector mounting design. (1.48” or 2.56” O-ring to O-ring injector length). When you looking for the pinnacle of performance, price, and quality, look no further Holley EFI. For more information on Holley’s High Ram intakes visit our website at Holley.com.
