Performance Radiator for BMW E60 525i 528i 530i (2006-2010) 3.0L

TIG-Welded Performance Radiator for 2006-2010 BMW 5 Series

Direct-fit performance radiator designed to optimize coolant flow and lower engine operating temperatures for N52-equipped E60 platforms.

The Stock 5 Series Cooling Shortcomings

The factory radiator in the E60 BMW 5 Series, while adequate for daily commuting, suffers from inherent design flaws as it ages. The OEM unit utilizes a plastic tank design crimped to an aluminum core. Over time, the constant thermal cycling from the N52's standard operating temperatures degrades these plastic end tanks, leading to stress fractures, weeping seals, and catastrophic coolant loss. Additionally, the standard tube-and-fin density limits optimal heat dissipation during high RPM driving or under heavy load, causing heat soak that forces the ECU to pull timing and reduce power output.

The Engineering Solution

This replacement performance radiator resolves the factory failure points through superior materials and improved thermal dynamics. Engineered with a 1-row, high-density core measuring 23.43 by 19.29 inches, it maximizes coolant exposure to incoming airflow without disrupting factory pressure thresholds. The construction utilizes premium grade aluminum that is 100% TIG welded, completely eliminating the failure-prone plastic end tanks and rubber crimp gaskets found on stock units. Featuring exact-spec 1.5-inch inlet and outlet diameters, it ensures turbulence-free fluid transfer and maintains standard system pressures. By enhancing thermal exchange efficiency, this radiator stabilizes operating temperatures, mitigating heat soak and maintaining consistent horsepower and torque under demanding mechanical conditions.

Common Questions

Will this fit my 2008 BMW 528i?
Yes. It fits 2008-2010 528i, 528xi and 528i xDrive sedans with the N52 3.0L and automatic transmission, plus 2006-2007 525i/525xi and 530i/530xi.

Does it fit the E61 wagon?
Yes, the 2006-2007 530xi wagon with the N52 3.0L and automatic transmission is covered.

How do I know it matches my car?
Look at the lower right of your radiator. If it has the extra hose fitting for the transmission cooler line, this radiator is a direct swap.

What's different from the factory radiator?
The tanks are aluminum and 100% TIG welded instead of plastic crimped to the core, with a 23.43 x 19.29 in high-density core and 1.5 in inlet and outlet.

Do I need to modify anything to install it?
No. It is a drop-in fit on the factory mounts and works with the factory sensors.
