Product Description

The Wagner Tuning B48/B58 Chargecooler Radiator Kit is a high-capacity cooling upgrade for BMW F-Series B48 and B58 models equipped with the factory water-to-air intercooler system.

The factory auxiliary chargecooler radiator can become heat-soaked during tuned use, spirited driving or track sessions, causing higher intake air temperatures and reduced performance consistency. Wagner’s uprated radiator is designed to increase cooling volume, improve thermal efficiency and maintain more stable charge temperatures under load.

Featuring an enlarged high-efficiency core, optimised bar-and-plate construction and CNC precision-welded aluminium end tanks, this kit offers improved heat dissipation, durability and reliability for both standard and modified B48/B58 engines.

Designed as a direct bolt-on upgrade using factory mounting points, the Wagner Chargecooler Radiator Kit works with the OEM water-to-air intercooler system and is suitable for fast-road, track and high-load applications.
