Spool Billet Manifold Top Mount Turbo Kit - G30 540i Gen 1 B58

Spool Performance Billet Manifold Gen 1 B58 540i Top Mount Turbo Kit Spool Performance is proud to introduce our one-of-a-kind top mount turbo kit featuring a 5-axis machined billet exhaust manifold. This process has allowed us to create a unique manifold that features ultra short runners providing maximum heat energy retention up-to the turbine while avoiding common issues with cast manifolds like cracking and increased weight. The 5-axis manufacturing process has also allowed us to create an extremely efficient flow by equalizing wastegate port design allowing for excellent boost control with a single 45mm wastegate. The result is a fast spooling and lightweight manifold that delivers almost nonexistent levels of backpressure and is easy to install. The modular nature of the manifold design allows us to offer these kits with a wide variety of turbo options.
