Couldn't load pickup availability
The CSF 8400C Race X is a liquid-to-air charge-cooling manifold for compatible Gen 2 B58 engines, supplied in custom finish. Its 15-row core has 25% more core volume than CSF’s 12-row 8200 manifold—not 25% more than every factory manifold.
The custom options select a complete manifold in the listed finish. A front -16 ORB water port supports alternative coolant plumbing, including single-pass or ice-box layouts. The included -8AN fuel rail and additional sensor provisions are intended for a build with separately planned fueling and cooling circuits.

Product FAQs
Will Race X fit a B58N or B58TU2 engine?
No. The listed exclusion includes B58N, B58TU2 and B58B30M2. Check the original manifold reference and engine configuration, not just the vehicle badge.
Are port-injection block-off bungs included?
No. Plan supplemental injectors or separately sourced compatible bungs. The included fuel rail does not include injectors.
Is installation straightforward on a 48V mild hybrid?
No. CSF specifies significant clearance work at the cylinder head and alternator plus an additional 8200S spacer. The spacer alone does not resolve the installation.
