CSF #8402 "No Limit" billet air-to-air competition intake manifold for the BMW S58 engine (M2 G87, M3 G80, M4 G82). Fully CNC-machined from 6061 billet aluminum with high-pressure o-ring sealing rated beyond 100 psi (7+ Bar) and a Thermal Rejection manifold spacer that cuts intake temperatures by up to 15%. Removing the charge cooler from the manifold frees up a much larger front-mounted intercooler, supporting extreme S58 builds of 1500+ WHP. Runners use integrated velocity stacks and modular top ports for 6 or 12 nitrous or methanol injectors, with a flange for a 77mm S55 throttle body.
