Description

High-Performance Race Manifold. The Holley GM LS3/L92 Single Plane EFI Split-Design Race Intake Manifold is engineered to deliver optimum airflow and power for high-powered GM LS engines. Designed specifically for racing and performance applications, it enhances power output primarily in the mid to upper RPM ranges, up to approximately 7000 rpm. Its split design facilitates easy porting customization, providing enhanced tuning flexibility.

Durable Lightweight Construction. Made from cast aluminum with a natural finish, this manifold features a robust split design with captured O-ring seals for a precise, leak-free fit. Rail mounting hardware is included for secure attachment (fuel rails sold separately). The standard 4150 throttle body flange accepts large throttle bores suitable for racing configurations.

Installation Made Simple. Installation is straightforward, requiring no drilling, due to integrated bolt locators and O-ring seals that simplify assembly. It is designed for direct bolt-on compatibility with LS3/L92 cylinder heads.

Warranty Coverage. This product includes a manufacturer’s limited 90-day warranty for added assurance.

Application. Specifically fits 2007-2008 6.2L Yukon models equipped with LS3/L92-style rectangle-port heads without modification.
