Ever since the first E30 series came along, BMW M3 has enchanted car enthusiasts around the world. The E90 series, that has been with us a few years, is no exception. By many elected the perfect combination of usability and performance. A real sports car, with room for passengers. With its well balanced chassis, its thorough construction and hefty V8, this is almost the perfect core for a race car. But only almost. Ascending liquid temperatures is one of few known issues with them. Do88 has analysed the reasons behind this, and developed a sustainable solution.

This comprehensive DO88 M3 Cooling Kit is ideal for both the clubman racer and track day enthusiasts to ensure you get the maximum performance from your BMW whilst protecting the engine from overheating. Developed and extensively tested in conjunction with a German Racing Team this Kit offers a significant upgrade compared to the original parts!

A manual gearbox vehicle does use the same original gearbox oil cooler as the DCT model, but the manual cars do not tend to have an oil overheating problem during hard driving found in the DCT gearbox model. If you have a manual gearbox car and wish to upgrade your gearbox oil cooler as well then you may still use our BIG-M3-DCT 4 piece kit.
