The CSF No Limit billet charge-air manifold relocates the charge cooler out of the intake manifold, removing the core-size limitation of every drop-in B58 cooler and freeing builders to run a much larger air-to-air or air-to-water intercooler. Fully CNC-machined from 6061 billet aluminum with internal velocity stacks and O-ring sealed construction rated beyond 100 psi, it is engineered to support 1500+ horsepower builds. A 77mm throttle-body flange, top-feed port injection configurable for 6 or 12 injectors, and modular ports for supplemental nitrous or methanol injection make it a competition-focused foundation for high-power B58 setups, and an integrated thermal-rejection spacer helps lower intake manifold temperatures.
