3.0T/4.0T High-Capacity Heat Exchanger

This MercRacing unit maximizes both surface area and coolant volume using the vehicle's full frontal area, resulting in significantly lower and more consistent intake air temperatures, even during repeated hard pulls. This heat exchanger features a multi-pass design with high-density fins for efficient heat dissipation and boasts an approximate 1-gallon coolant capacity, substantially exceeding the OEM unit's volume. Constructed from all-aluminum with TIG-welded seams, it includes a crash bar mount with integrated hardware. For easier installation and maintenance, it features an integrated bleed port for air purging and drain holes on the bottom header to prevent water accumulation. Customers consistently praise this unit for its performance, capacity, fitment, and value, often noting it outperforms more expensive premium units in sustained heat rejection. Installation notes indicate that vehicles equipped with a factory dynamic steering cooler, typically visible through the top of the grille, will require this unit to be relocated. MercRacing recommends their Compact Fluid Cooler for this purpose. The product includes the heat exchanger itself, mounting brackets and hardware, and necessary silicone hose(s) and clamps.
