3-Row Aluminum Intercooler Heat Exchanger — F30/F32/F22 B48/B58

The engineering details here matter. Tapered entry and exit points on the end tanks smooth coolant flow in and out of the core, reducing turbulence and maximizing throughput — a benefit that compounds on xDrive models, where the transmission oil cooler sits directly upstream of the heat exchanger and demands every bit of thermal efficiency the system can offer. CNC machined mounting pins and brackets match OEM tolerances exactly, and the quick-connect inlet and outlet fittings are plug-and-play compatible with the factory hose connections. No drilling, no fabrication, no headaches.

Fitment spans the full 2014–2018 F-Series lineup running B38, B46, B48, or B58 engines — from the F20 120i and 125i through the F30 320i, 330i, and 340i, and across the F22, F23, F32, F33, F34, and F36 body styles in both standard and xDrive configurations. Whether you're running a tune on a 340i or pushing a 440i through summer track sessions, this unit installs in a single afternoon with basic hand tools.

Every unit ships 100% leak tested and durability verified, with a hand-welded and machine-stamped construction rated to handle fluid temperatures up to 302°F (150°C). A professional installer is recommended if you're unfamiliar with the cooling system layout, but for experienced DIYers, this is one of the most straightforward thermal upgrades available for the B-series platform.
