CSF High-Performance Heat Exchanger – Toyota GR Supra (A90/A91)

OVERVIEW

The CSF #8154 High-Performance Heat Exchanger replaces the factory air-to-water heat exchanger on the A90/A91 Toyota GR Supra, in both 3.0L and 2.0L form. It significantly reduces intake air temperatures (IATs) for maximum performance, with much faster heat-soak recovery than the OEM unit, and improves air flow to the rest of the cooling stack for lower engine coolant and engine oil temperatures.

The exchanger is built around a 2-row, 42mm ultra-high-performance core using CSF's exclusive B-Tube technology paired with an ultra-efficient multi-louvered fin. Construction is 100% all-aluminum TIG-welded, with CNC-machined mounting brackets and OEM-style "quick connect" inlet and outlet connections. A rock guard and a transmission oil cooler mounting kit are included in the box, an industry exclusive at this price point.

Fitment is a true drop-in: the unit mounts in the factory location and accepts the OEM quick-connect lines with no cutting or trimming. CSF's design has been tested and proven by its global network of R&D partners, including leading time attack teams, tuners and turbo kit manufacturers.
