CSF Charge-Air Cooler Manifold - Machined Billet Aluminum

CSF's billet charge-air cooler manifold for the B58, machined from solid aluminum rather than cast. Replaces the factory air-to-water unit with dramatically more core volume and a far more even flow distribution across all six runners, which is what keeps charge temps flat on high-boost builds. This is a serious piece for cars making real power, not a mild bolt-on. Not CARB legal.
