Upgrade to RVNG B58 Triple Pass Heat Exchanger
The OEM B58 heat exchanger is a single-row unit just 27mm thick. The RVNG High-Performance B58 Heat Exchanger steps up to a massive 2-row core measuring 68mm, built with advanced B-Tube technology, with a precision-engineered tank design that drops the larger core into the OEM cooling housing with no modification.
Its triple-pass flow design routes coolant through the heat exchanger three times before returning to the manifold charge cooler — dramatically improving heat-transfer efficiency for the lowest possible outlet water temperature. Where the OEM unit and many aftermarket options use single-pass designs, this triple-pass system delivers superior cooling for sustained power and reliability.
