Mishimoto BMW E30/E36 X-Line Performance Aluminum Radiator


The Mishimoto performance aluminum radiator for the 1988-91 BMW E30 and 1992-1999 BMW E36 cars with 6 cylinder engines is a big improvement over the OEM radiators and a great track upgrade.

An ideal upgrade for the brittle stock radiator, the Mishimoto E30/E36 X-Line Performance Aluminum Radiator provides your vehicle with enhanced reliability and improved cooling efficiency. BMWs are known to have frequent cooling-related failures due to the use of numerous plastic components throughout the cooling system. A simple coolant leak can result in overheating, accelerated engine wear, or head gasket failure.

Whether you have a daily-driven E36 M3 or an M20 spinning a large turbocharger, this radiator provides ideal temperatures on and off the track. Most people overlook the importance of installing an upgraded radiator in their vehicle. This X-Line Performance Aluminum Radiator reduces coolant temperature by 30 degrees Fahrenheit (16.62 degrees Celsius) and is 20% more efficient than the stock radiator. Along with providing an increased coolant capacity of 91%, this radiator improves heat dissipation, which is beneficial for both stock and modified applications.

If your BMW is a daily driver, autocrosser, or track car, you can never have "too much cooling". The stock BMW radiators are multi-piece plastic/aluminum units with tiny little cores but the Mishimoto is just bigger and better in every way.

Vorshlag has installed Mishimoto aluminum radiators on countless cars - Miatas, BMWs, Mustangs, and Subarus - including our shop built, NASA TTU classed BMW E36 V8, shown above. With a 490 whp 7.0L V8 we added some extra heat to a normal E36, and this Mishimoto radiator was the best cooling upgrade we performed. The price is impossible to beat, the craftsmanship is excellent, and with a lifetime warranty? A Mishimoto radiator is the first thing we add on any tracked E36 or V8 powered BMW.

We have lost count of how many E36 BMW V8s we have built, but every one of them used a Mishimoto radiator. From 350 whp to 540 whp, these have never disappointed us. They bolt in and handle the heat, no problem.


This is a 1995 BMW M3 was built for track use and the Mishimoto radiator was one of the first upgrades we made to the car for better track cooling. We also added a Mishimoto fan to this unit and at 425 whp it ran like a top with this setup. Mishimoto all we use on V8 swaps...
