Holley releases their Single-Plane-Design EFI Racin Intake Manifolds for GM Gen 3 LS Engines. The intake manifolds are designed for cathedral-port cylinder heads and 4150-style square bore throttle bodies and work well for race/high-performance applications. Holley takes out most of the headache with a two-piece configuration that makes them easy to disassemble for custom porting and port-matching shoulder-bolt locators and captured O-rings make putting it back together a breeze.
Holley Single-Plane Split-Design EFI Race Intake Manifolds are available in either silver or black finishers. With ab A-B height of 7.32 inches (0-degree carb-flange angle) this product makes 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.
