B58 Charge-Cooler Intake Manifold w/ Port Injection

Billet manifold · integrated PI · sourced to order

The real flagship B58 upgrade. The factory charge cooler is a water-to-air core built into the intake manifold — this replaces the whole unit with a billet manifold carrying a larger water-to-air core and integrated port-injection rails, so high-ethanol, big-turbo builds get the fuel and the charge cooling in one honest part. No chassis charge piping to disturb: everything stays on the engine. Sourced to order — we confirm gen1/gen2 fitment, finish and PI rail sizing with your build before the order is placed.
