Race X is CSF's no-compromise charge-air cooler manifold for Gen 2 B58 cars in serious competition. The standard CSF Super Manifold is already more than enough for most builds, but once you reach 1,000hp+ most aftermarket manifolds run out of flow and cooling capacity. Race X answers that with a 25% larger core, an optimised water flow system and extra parameter ports.
The core can be run in dual or single-pass configuration, and a large -16 ORB front port is optimised for ice box setups. Race-proven on some of the fastest B58 drag cars in the world, it is the largest and most versatile B58 manifold available, and comes complete with a KIYLEX Thermal Rejection Spacer and a full, clearly labelled hardware kit.
Please note: this is a racing product. Some modifications are required and it should only be installed by a skilled technician familiar with the B58 engine platform.
Please note: available in Raw Billet Aluminium, Thermal Dispersion Black (Cerakote) or a Custom Finish of your choice. Custom finishes are made to order – please contact us to confirm your colour/finish and lead time before ordering.
Please note: for single-pass or ice box setups, CSF recommend Brown and Miller (BRMS) fittings AC-16-M3-120 (black) or AC-16-M4-120 (blue), with a maximum fitting angle of 120 degrees (not included).
