LS 102mm Intake Manifold

The Velocity LS 102mm Fabricated Aluminum Intake Manifold is engineered to enhance both the look and performance of Chevrolet Small Block V8 Gen III/IV (LS Based) engines. Designed with a 102mm throttle body opening and velocity-stacked intake runners, it facilitates maximum airflow for high-horsepower applications. The manifold itself is constructed from durable 3.5mm thick T-6061 aluminum, with TIG welding throughout for exceptional strength and reliability. Its head flanges are 7/16" thick, allowing the plenum to handle up to 25lbs of boost. This intake manifold features intelligent design elements, including individual port o-rings for a secure seal to the cylinder heads. The angled, low-profile design, along with a recently lowered overall height, aims to improve fitment in various applications. The black anodized finish provides a clean and custom appearance in the engine bay. It includes port o-rings and hardware for installation. Fitment is for Chevrolet Small Block V8 Gen III/IV (LS Based) engines, specifically listing compatibility with 4.8L (LR4), 5.3L (L33, L59, LM4, LM7), 5.7L (LS1, LS6), and 6.0L (LQ4, LQ9, LS2) displacements. It is important to note that this manifold fits LS-based engines with a "cathedral" intake port shape only. Due to its transverse engine configuration, fitment on the LS4 would require significant modification.
