What are the benefits of using -10 AN lines with this oil cooler?

Using -10 AN lines allows for a more modern and reliable connection compared to the older OEM rubber and hardline hoses. These lines are typically easier to source and can offer better fluid dynamics for improved cooling efficiency.

Does this oil cooler come with everything needed for installation?

The oil cooler comes complete with a fitting kit that supports both OEM style connections and -10 AN male connections. For specific E30 models outside the direct fit range, a separate BMW retrofit kit with brackets, grommets, and screws is required.

Can this oil cooler be used for engine swaps into an E30?

Yes, this CSF oil cooler is designed to fit other M20 engine swap setups. It's also noted to be adaptable for various engine swaps, including S54 BMW motors and LS engine swaps, helping to keep those engines cool.

Product Details

Starting with a rugged bar/plate design, this CSF oil cooler is built to handle the demands of your BMW E30. It's developed with a BMW restoration partner to offer a drop-in fit, making it a solid upgrade over the original 25-year-old cooler. This isn't just about replacing a worn-out part; it's about improving your engine's ability to stay cool, whether you're driving it daily or pushing it on the track.

One of the standout features is the included fitting kit, which lets you run modern -10 AN lines instead of the older, often corroded, and hard-to-find OEM rubber and hardline hoses. This cooler also boasts increased cooling capacity and variable inlet/outlet fittings, all housed in a cast end tank design with a matte black finish. It's a well-built solution designed to give your classic German car the efficiency and durability it deserves.

This oil cooler is designed as a direct fit for the 1988-1992 BMW 325i, 325iX, and 325is. It can also be adapted for other M20 engine swaps, and with a specific BMW retrofit kit, it can fit 1984-1987 E30 models and the E30 M3.
