Performer RPM Intake Manifold -GM LS1

The Performer RPM Intake Manifold for GM LS1 engines represents the gold standard for bolt-on power gains in LS-series applications. Engineered by Edelbrock, a name synonymous with high-flow induction since 1954, this dual-plane aluminum manifold delivers measurable torque increases across the RPM band without requiring extensive engine modifications. Whether you're upgrading a street Corvette, Camaro, or truck platform, the Performer RPM bridges the gap between stock restrictive designs and full race competition intake systems—making it the choice for enthusiasts seeking reliable, repeatable performance gains.

The square-bore, dual-plane design optimizes air velocity and distribution across all eight cylinders, improving combustion efficiency and low-to-mid-range throttle response without sacrificing top-end power. Constructed from lightweight cast aluminum and finished in natural (uncoated) form, the manifold integrates timing control provisions for precise tuning and compatibility with both stock and aftermarket fuel injection systems. The dual-plane runner configuration separates cylinder groups to reduce reversion and cross-firing, a critical factor that separates engineered performance parts from generic castings. At 23.94 pounds, it adds minimal rotating mass while providing the structural rigidity required for sustained high-RPM operation.

This manifold is purpose-built for GM LS-series engines and requires direct bolt-on fitment to OEM or aftermarket cylinder heads—no adapters or modifications needed. Performance gains typically range from 15–25 horsepower and 20–35 lb-ft torque depending on supporting modifications, fuel octane, and engine tuning. Installation demands basic hand tools and gasket sealant; most builds complete in under an hour on a lift. Compatibility spans naturally aspirated LS1, LS2, LS3, and LS9 variants when paired with appropriate manifold gaskets and clamps, making it a versatile platform upgrade for street, strip, or road-course applications seeking dependable mid-range grunt without exotic complexity.
