BMW G-Series B48 / B58 Rvng 68mm Heat Exchanger (Also Fits Supra)

The Rvng high-efficiency heat exchanger replaces the factory 25 mm single-row unit on G-series B46, B48 and Gen 2 / Gen 3 B58 cars with a 68 mm dual-row core.

Why you need it

On tuned B58 cars the factory charge-air cooling heat-soaks fast, intake temps climb and the ECU pulls power, sometimes into limp mode. Rvng's core is over 2.5x as thick with much more coolant volume and surface area, for stable intake temps during repeated pulls and track sessions.
