CSF Heat Exchanger - A90 GR Supra

The factory heat exchanger is the first thing to give up on a tuned B58, and once intake temps climb the ECU pulls timing and you lose the power you paid for. CSF's replacement uses a substantially thicker core with more coolant volume, holding charge temps down through repeated pulls instead of heat-soaking after one. Direct fit to the OE mounting points and hose routing.
