Mishimoto Performance Aluminum Radiator for Select BMW & Toyota 2019-2026 (3.0L) MMRAD-SUP-20

Fits select 2019-2026 BMW 330e, 330i, Z4, and Toyota GR Supra (3.0L).

Maintain optimal operating temperatures on the track or the street with the Mishimoto Performance Aluminum Radiator. Designed specifically for the A90 Supra and its BMW G20/G29 chassis counterparts, this radiator replaces the slim factory core and failure-prone plastic end tanks with a robust, TIG-welded all-aluminum construction. The 1.65-inch thick core provides a 31% increase in core volume over the stock unit, significantly increasing cooling capacity for the B58 engine.

The updated tube-and-fin design features a 57% increase in external fin surface area to maximize heat dissipation, especially when paired with Mishimoto Performance Auxiliary Radiators. For added durability under high-pressure conditions, Mishimoto incorporates strutted tubes throughout the core to prevent flex and drastically reduce the risk of leaks or breaks. This radiator features a polished finish and includes the Mishimoto Lifetime Warranty for a reliable, worry-free installation.
