CSF Billet Charge-Air-Cooler Manifold — B58 Gen1 (F-chassis)
CSF billet charge-air-cooler manifold for the Gen-1 B58 (F-chassis). Replaces the OEM plastic manifold and its integrated water-to-air charge cooler with a CNC-billet manifold and a larger cooler core.
What CSF changes
Billet aluminum with roughly twice the cooling rows of the factory core, machined intake runners that seal to the OEM O-rings, and a thermal-rejection competition spacer. All fittings included; pairs with the front heat exchanger.
Finishes
Default is the Thermal Heat Dispersion coating — an emissivity coating that helps the part shed heat. Also available Raw, or in Esse Werks colors — Black, White, or Orange. Choose above.
