Holley is pleased to announce the release of their Single-Plane Split-Design EFI Race Intake Manifolds for GM Gen 3 LS engines. They're perfect for race and high-performance LS engines and are designed specifically for cathedral-port cylinder heads and 4150-style square-bore throttle bodies. They're lighter than ordinary split race intakes and cost one-third to one-half as much. The two-piece configuration makes them easy to disassemble for custom porting and port-matching; shoulder-bolt locators and captured O-rings make reassembly simple and precise. 

Race-bred Holley Single-Plane Split-Design EFI Race Intake Manifolds are available in both silver and black and feature an A-B height of 7.32 inches (0-degree carb-flange angle) for plenty of under-hood clearance and cathedral ports 3.28 inches tall and 1.10 inches wide. They're ideal for EFI applications with displacements from 5.3L to 6.2L and deliver optimal performance across your entire RPM range and maximum power up to 7,000 RPM. To ensure a fast, hassle-free installation, the fuel rails, O-rings, and all the necessary fasteners are included.
