Past roughly 1,000 hp on a B58, most aftermarket charge-air cooler manifolds run out of airflow and cooling capacity. The Race X is CSF's answer for those builds. It uses a 25% larger core, extra ports and a front water plate set up for single-pass or ice box cooling.

What you get

  • 25% larger core for more airflow and cooling at very high power.
  • Five ports total, two 1/4" NPT added to the standard three 1/8" NPT, for extra sensors or a vacuum source. Plugs are included.
  • Front water plate with a -16 ORB bung for single-pass or ice box setups.
  • Recessed rear section so the spin-on oil filter can be changed without removing the manifold.
  • Raw billet aluminum finish.

Good to know

  • CSF recommends Brown and Miller -16 fittings at no more than 120 degrees on the front water plate.

Start with a tune. It is the biggest gain per dollar on any B58. Then add a downpipe and a Stage 2 map, then an upgraded high-pressure fuel pump (HPFP) and an ethanol blend. Only after that should you think about a bigge
