Spool Performance Billet Manifold Top-Mount Turbo Kit

For BMW Gen 2 B58 Engines | Up to 1400HP | Plug-and-Play Solution

Spool Performance proudly presents a game-changing innovation for B58 enthusiasts—the Billet Top-Mount Turbocharger Kit for BMW Gen2 B58 engines. Featuring a 5-axis CNC machined billet exhaust manifold, this kit sets a new standard for turbo upgrade systems. Designed for maximum flow, minimal backpressure, and superior durability, the Spool top-mount kit is lightweight, modular, and engineered for peak performance.

🔧 Engineered for Power & Precision

Unlike heavy and failure-prone cast manifolds, our 5-axis machined billet steel alloy manifold ensures:

• Ultra-short runners for maximum heat energy retention to the turbine

• Low turbulence and ultra-low backpressure

• Optimized twin-scroll channels and equalized wastegate flow

• Reliable boost control with a single 45mm Turbosmart wastegate

This results in faster spool, higher efficiency, and a compact install footprint—ideal for high-horsepower, track, or street builds.
