Description
Engine Intake Upgrade. The Holley GM LS3/L92 Single Plane EFI Intake Manifold in black ceramic coating enhances engine airflow efficiency and performance for GM LS Gen III engines. Designed specifically for EFI systems, it promotes a broad torque curve and optimal power delivery between 2500 and 7000 RPM, improving vehicle responsiveness and power output for both naturally aspirated and forced induction setups.
Premium Construction and Finish. This manifold is crafted from cast aluminum with a durable black ceramic coating for corrosion resistance and long-lasting use. The efficient casting design ensures consistent wall thickness and high-quality manufacturing, making it suitable for use with centrifugal superchargers, turbochargers, or nitrous oxide systems.
Installation Ease. Installation is straightforward, requiring no additional drilling, and includes mounting bolts, washers, and Viton O-ring intake to cylinder head gaskets. It is important to note that this manifold does not work with factory fuel rails and requires the Holley Fuel Rail Kit 534-218 for proper installation.
Warranty Coverage. Backed by a manufacturer’s limited 90-day warranty, this intake manifold offers assurance of quality and workmanship.
Application Fitment. Specifically designed to fit the 2007-2008 6.2L Yukon equipped with LS3/L92 style rectangular port cylinder heads, ensuring a precise and reliable fit for this vehicle configuration.
