Keep your A90/MK5 Toyota GR Supra 3.0L running at peak performance with the Pinnacle Tuning Performance Auxiliary Radiator Pack. The A90 Supra has cemented itself as a modern tuning icon, but even with BMW engineering, elevated coolant temperatures can quickly cut a track session or spirited drive short. Our solution is designed to keep the B58 operating at optimal temperatures under the most demanding conditions.
Pinnacle Tuning replaces the restrictive factory auxiliary radiator with a fully aluminum, TIG-welded unit, eliminating the weak plastic end tanks found on the OEM core. Built to handle street, track, and drag use, the upgraded radiator features a significantly thicker core, increasing total core volume by 30% over stock.
An advanced tube-and-fin design boosts external fin surface area by an impressive 180%, delivering exceptional heat dissipation—especially when paired with a performance aluminum main radiator. For long-term durability, strutted tubes are integrated throughout the core to improve structural integrity and drastically reduce the risk of leaks or failure.
Finished in a sleek polished aluminum, the Pinnacle Tuning Performance Auxiliary Radiator Pack offers both function and form, making it a must-have cooling upgrade for any serious A90 Supra build.
