The Hurricane GM LS1/LS2/LS6 Single-Plane Intake Manifold is a high-performance upgrade for GM LS Gen 3 and 4 engines with LS1/LS2/LS6 cathedral port heads. Crafted from cast aluminium with a natural finish, this intake manifold is designed to operate within a wide rpm range of 2500-7000rpm, making it ideal for high-performance applications. Featuring a square bore design, it accommodates four-barrel carburettors and throttle bodies. The manifold comes equipped with necessary o-rings for a secure installation. With its cathedral port design, this intake manifold optimises airflow and enhances engine performance. If you're building a track-ready machine, the Hurricane GM LS1/LS2/LS6 Single-Plane Intake Manifold is a must-have upgrade for your LS-powered vehicle. Calflow manifolds are cast in high pressure steel dies rather than the pour-in sand molds used by other aftermarket manifold manufacturers. This type of tooling costs 2-3 times more than conventional sand-cast patterns, but the finished product is worth the additional expense. And because the cores (which form the internal ports and water passages) are mounted in steel instead of sand during the casting process, there is no chance of any core shift, which sometimes go undetected in sand castings.
