CSF has launched a high-performance all-aluminum Front Mount Heat Exchanger upgrade for the A90/91 Toyota Supra (and select BMW G-Series models) to address the overheating issues of the BMW B58 engine’s charge air cooler system. After six months of development, this upgrade combats heat soak, which has plagued Supra track enthusiasts, often leading to high intake air temperatures, power cuts, and limp mode. With power mods pushing up to 800whp, this new solution ensures sustained performance by managing the excessive heat that limits the stock system’s efficiency.
