Sinper EFI Fabricated Intake GM LS1/LS2/LS6

The Holley Sniper EFI Fabricated Intake manifold for GM LS1/LS2/LS6 engines is a purpose-built, plug-and-play fuel injection solution designed for LS-series engine builders and performance enthusiasts seeking integrated intake and fuel rail functionality. This aluminum manifold features a 92mm throttle body flange, black anodized finish, and comes complete with fuel rails—eliminating the need for piecing together separate components and reducing installation complexity.

The Sniper EFI platform is engineered around the Holley LS-compatible fuel injection ecosystem, delivering consistent fuel atomization across all engine speeds. The 92mm throttle body flange matches OEM LS intake port geometry, ensuring optimal airflow characteristics without flow restrictions common in adapter-based installations. Aluminum construction with anodized coating provides durability and corrosion resistance in engine bay environments, while the included fuel rails integrate cleanly with the manifold casting to simplify wiring and plumbing. The complete kit approach—manifold, rails, and core Sniper EFI architecture—minimizes tuning variables and reduces troubleshooting time during initial startup and baseline calibration.

This intake system serves LS engine builds across street performance, weekend track duty, and dedicated race applications where integrated fuel delivery and manifold design matter. Engine builders and LS swap enthusiasts rely on Sniper EFI manifolds to streamline installation on naturally aspirated and forced-induction platforms. The 18.23 lbs weight and compact envelope (15 × 12 × 21.25 inches) facilitate fitment in engine bays with space constraints, including retrofits into vehicles originally equipped with carbureted or older fuel injection architectures.

The Sniper EFI product family has established itself as a solid mid-tier alternative within LS intake ecosystem, offering factory-level integration without premium pricing. Buyers evaluating this manifold typically compare it against traditional cast-iron intakes (heavier, higher thermal mass) and competing fabricated aluminum systems (fewer included features). For builders prioritizing fuel rail integration and simplified assembly, this Holley offering delivers verified compatibility across LS1, LS2, and LS6 platforms with the fuel delivery infrastructure included.
