Holley EFI Intake Kits

Holley EFI Intake Kits: Engineered for EFI-First Performance

When it comes to purpose-built electronic fuel injection intake solutions, few names carry the weight of Holley EFI. Their lineup of intake kits isn't adapted from carbureted roots — these manifolds and complete kits are designed from the ground up around modern EFI systems, giving builders a cohesive, performance-optimized package rather than a patchwork of mismatched parts.

A Platform-First Approach

What separates Holley EFI's intake kits from generic aftermarket options is their deliberate, engine-platform strategy. Holley has developed product ranges designed for specific engine families, with Hi-Ram offerings catering to customers running Chevrolet LS and LT, Ford Coyote, 302 and 351 Windsor, and Gen III Hemi motors — and more recently expanding into classic small-block Chevy applications. This means every kit is engineered around the specific port geometry, throttle body sizing, and RPM characteristics of a given engine rather than relying on a one-size-fits-all design.

Key Product Lines

Holley EFI organizes its intake kit catalog into several well-defined families, each targeting a different build profile:

• Hi-Ram Intake Kits – The Hi-Ram EFI intake manifold kits feature a 105mm LS Gen IV-type throttle body flange plenum top, and a -10AN fuel rail kit is included. These tall-deck, high-flowing designs favor peak horsepower and are popular in drag and high-RPM street/strip builds. Available for LS3/L92, Big Block Chevy, Small Block Chevy, and Gen III Hemi applications.
• Lo-Ram & Ultra Lo-Ram Intake Kits – Designed where under-hood clearance is critical. With an opening that accepts Holley's 105mm EFI throttle body, the Lo-Ram intake designs give LS owners what they need to make big, boosted power. The castings are contoured to remove unnecessary weight and utilize rubber gasket solutions around the ports and lid openings to maximize sealing and serviceability. Holley's LS1/2/6 cathedral port and LS3 rectangular port Lo-Ram and Ultra Lo-Ram intake manifold kits offer finishing options that make them a versatile manifold option for nearly any application.
• Mid-Rise Intake Kits – Designed for all GM LS Gen III or IV engines equipped with LS3/L92 style rectangular ports, the Mid-Rise EFI Intake Manifold Kit targets a 1,500–6,500 RPM power band — making it an outstanding choice for street-driven performance vehicles that need strong pull across a wide range.
• Sniper EFI Fabricated Sheet Metal Intake Kits – These Race Series manifolds feature 5mm T6061 sheet aluminum construction, a 90mm throttle bore opening, 100% TIG-welded seams inside and out, and a removable top for ease of inspection, modification, and sensor addition. Each manifold is ready to bolt on out of the box, designed to accept Holley's Sniper high-flow throttle bodies, and includes a high-flow fuel rail kit, TB spacer, and removable top.

Complete Kit Philosophy

Holley EFI's intake kits distinguish themselves by delivering complete, bolt-on packages rather than bare manifolds. Fuel rails, mounting hardware, throttle body provisions, and gasket solutions are bundled together so builders can focus on installation rather than sourcing individual components. Cast-aluminum construction makes these kits a cost-effective alternative to billet or fabricated sheet-metal intakes and opens up options for custom porting and forced induction.

Whether you're building a street/strip LS swap, refreshing a classic muscle car with a modern EFI drivetrain, or pushing a boosted platform to its limits, Holley EFI's range of intake kits offers a well-supported, ecosystem-friendly solution that integrates seamlessly with Holley's own ECUs, throttle bodies, and fuel system hardware.
