DESCRIPTION:

Upgrade the high-RPM airflow and fuel-system capability of your 2016-2024 Chevrolet Camaro SS LT1 with the Holley EFI Hi-Ram Intake Manifold with Port EFI Provisions and Fuel Rails. Designed for the GM Gen V 6.2L LT1, these manifolds allow supplemental port fuel injection to be used alongside the factory direct-injection system. Part number 300-141 features a 92mm longitudinal LS-style throttle body opening, while part number 300-140 features a larger 105mm opening. Holley’s modular Hi-Ram design features approximately 6.5-inch runners, large-radius runner entries, optimized runner taper and cross-sectional area, and a 549-cubic-inch plenum. Both versions have an advertised 3,500-8,000+ RPM power band and include anodized, laser-etched fuel rails with dual injector mounting positions, making them well suited for modified naturally aspirated and forced-induction LT1 combinations requiring additional fueling capacity.
