The CSF “No Limit” B58 Air-to-Air Billet Competition Manifold is engineered for serious high-horsepower B58 builds where airflow capacity, charge air efficiency, and durability are critical. Developed alongside Custom Plenum Creations (CPC), this manifold removes the factory charge cooling limitation found in OE-style manifold designs and opens the door for larger front-mounted intercooler solutions in extreme performance applications.

Purpose-built for racers and high-output street builds, the CSF B58 billet manifold is designed to support substantially higher power levels than conventional drop-in manifold options. By separating the cooling function from the intake manifold itself, this system allows for far greater flexibility in intercooler configuration while improving airflow potential for builders pushing the B58 platform well beyond stock limitations.

Precision CNC-machined from solid 6061 billet aluminum, the manifold features optimized plenum volume, refined runner geometry, and integrated velocity stacks to promote balanced airflow into each cylinder. High-pressure O-ring sealing, modular runner ports, and top-feed port injection capability make this a motorsport-grade solution for advanced B58 applications that demand strength, consistency, and scalability.
