CSF Billet B58 Charge Air Cooler Manifold for BMW Gen 1

The factory plastic charge air cooler manifold on the Gen 1 B58 engine is prone to failing at the crimp-on gasket joints under high boost and suffers from heat soak during aggressive driving. The CSF 8300 replaces the OEM unit with a 100% TIG-welded billet aluminum manifold designed to withstand extreme pressures while maintaining lower intake air temperatures. This manifold features a motorsports-grade bar and plate core with 12 rows of water cooling, doubling the capacity of the 6-row factory unit.

Key Features

• High-performance bar and plate air-to-water intercooler core with 12 cooling rows
• Included KIYLEX Thermal Rejection Manifold Spacer to reduce heat transfer by up to 15%
• Integrated air divider in the inlet tank for even airflow distribution to all cylinders
• Top-feed port injection fuel rail included with individual bungs on each runner
• Six 1/8 inch NPT ports for individual cylinder nitrous or methanol injection
• Recessed design with counter-balanced protrusion for easy oil filter access without sacrificing airflow
• Integrated sensor pad with three 1/8 inch NPT ports for vacuum or data logging
• Individual 1/8 inch NPT breather ports for simplified system bleeding
• Raw billet aluminum finish for a professional motorsport aesthetic
