The Holley EFI Hi-Ram intake redefines performance for the new GM direct-injected Gen V 6.2L LT1 engine. Engineered with a modular design, this manifold allows effortless disassembly for custom porting, accommodating multiple tops, or tailored induction systems. Each runner boasts a generous radius where it meets the plenum, featuring an optimized taper and cross-sectional area to excel in diverse engine configurations. The optional injector bosses on the intake runners open up possibilities for enhanced performance by integrating additional injectors with the factory direct injection. For the pinnacle of performance, value, and quality, trust in Holley EFI.
