CSF "No Limit" Billet Air-to-Air Competition Manifold - BMW F9X X3M/X4M, G8X M2/M3/M4

Product Details

The CSF #8402 "No Limit" Billet Manifold is a specialized performance solution designed for the BMW S58 engine, found in the G80 M3, G82 M4, and G87 M2. Developed in collaboration with Custom Plenum Creations, this manifold is engineered for extreme-duty drag racing and high-horsepower builds aiming to surpass the 1500 WHP mark. By removing the internal charge cooler found in factory-style manifolds, the #8402 allows racers to utilize a significantly larger front-mounted intercooler (Air-to-Air or Air-to-Water). This design eliminates the flow restrictions and heat soak common in drop-in manifolds, providing a "no limit" ceiling for boost and power. It has been track-proven on the world’s fastest S58 vehicles, contributing to world-record 7-second quarter-mile passes.
