Wagner Tuning Radiator Kit – Toyota GR Supra (A90) / BMW Z4 (G29)

OVERVIEW

The GR Supra and its sister car, the BMW Z4 G29, cool their charge air through a water-to-air core inside the intake manifold, so the size of the low-temperature coolant loop sets the ceiling on sustained power. Wagner Tuning's radiator kit enlarges that loop — 16.70 liters against the factory 7.70 — keeping intake temperatures stable through consecutive pulls or a full session rather than climbing after the first.

Wagner lists the kit for both the 3.0 B58 and the 2.0 B48 versions of each car.
