Mishimoto Performance Heat Exchanger - Toyota GR Supra/BMW Z4

OVERVIEW

Keep your intake air temperatures down with the Mishimoto Performance Heat Exchanger, designed specifically for the B58-powered GR Supra and Z4 M40i. BMW and Toyota integrated the air-to-water intercooling system directly into the intake manifold, but the factory heat exchanger leaves cooling headroom on the table — this direct upgrade closes that gap.
