High-Performance Heat Exchanger / Chargecooler radiator for BMW F22, F23 220i, 230i, 230iX, M240i, M240iX models with B46, B48 and B58 engines.
B46 / B48 / B58 engines feature an innovative cooling system with the intercooler built directly into the intake manifold. This setup is cooled by a separate, front-mounted water radiator, commonly referred to as a heat exchanger or chargecooler radiator. For stock or lightly tuned setups, the factory radiator performs well enough, so upgrading it may seem unnecessary. However, if you’re aiming for higher power levels with Stage 2 or Stage 3 tuning, or driving aggressively enough to cause heat soak in warm climates, upgrading to a high-performance heat exchanger can make a noticeable difference. This upgrade helps maintain low intake temperatures, enhancing combustion efficiency and supporting your engine’s long-term health.
Our high-performance heat exchanger provides a 120% increase in core water volume compared to the OEM radiator, maximizing heat transfer and significantly reducing air-charge temperatures. This added cooling capacity minimizes temperature fluctuations and prevents heat soak, even under the most demanding driving conditions. Built for long-lasting durability and reliable performance, it includes a specialized thermally conductive, anti-corrosive coating and advanced fin design that channels airflow efficiently, allowing cool air to flow freely and support effective cooling of surrounding components, including the main engine radiator.
Upgrade to the KPerformance heat exchanger and experience unparalleled cooling performance that keeps your vehicle running at its best, even in the toughest conditions.
