AIRTEC's uprated oil cooler kit for the E90, E92 M3, is designed for both track and fast road use. Developed through extensive experience creating high-performance oil cooling solutions, this kit is a direct replacement for the factory cooler, engineered to make the most of the available space in the original location.
Featuring a 79% larger core and a 17% increase in frontal area compared to standard, the AIRTEC oil cooler provides a significant improvement in cooling efficiency and overall capacity. This allows the engine to maintain stable oil temperatures during sustained hard use, reducing the risk of heat-related performance loss.
The comprehensive kit reuses the original oil line fittings for a straightforward installation and includes new O-rings, replacement bolts, and a detailed fitting guide. Finished to AIRTEC’s high standards, this upgrade is an essential addition for any modified or track-focused E9x M3.
Please note: 2007 or early 2008 models will require the original oil line connectors to be modified OR replaced - see instructions above
