RPM Tuning B58 Charge Cooler Manifold
For BMW F-Series B58 Engines (Gen 1)
Take control of your intake temps and unlock consistent performance with the RPM Tuning Charge Cooler Manifold — our high-performance solution for the B58 Gen 1 platform. Designed for high-boost applications, this upgraded unit replaces the restrictive factory water-to-air intercooler with a larger, freer-flowing, and more thermally efficient design.
🔧 Key Features:
-
Massively Increased Core Volume: ~132% larger than stock for significantly improved heat rejection
-
High-Performance Internal Air-to-Water Core: Maintains consistent intake air temps even under repeated full-throttle pulls
-
CNC-Machined Billet Inlet Flange: Engineered for durability under pressure, with OEM sensor and hose compatibility
-
Multiple AN Fittings for Meth or Port Injection: Pre-machined ports for plug-and-play expansion
-
Optimized Flow Distribution: Equal airflow to all cylinders to reduce the risk of knock or lean conditions
-
Direct Fitment: Compatible with stock and upgraded throttle bodies, sensors, and OE coolant lines
📈 Performance Gains:
