Mishimoto BMW E30/E36 X-Line Performance Aluminum Radiator

Being pleased with our design in comparison to the stock unit, it was time to put this radiator to the test and see how the improvements would impact cooling efficiency. The first true test for this radiator would be fitment. Although this product was designed based off of dimensions from the stock radiator and the engine bay of an E36 M, we still had yet to drop this unit into a vehicle to ensure that all components bolted into position properly. We snagged the keys to our test vehicle from our videographer and easily dropped our prototype into place. Check out a few shots of this radiator installed!

As you can see, everything fit perfectly with this radiator. This vehicle is still utilizing the stock mechanical fan and everything clears as it should with plenty of room for engine movement. You will also notice that all factory shrouding and ducts also function with this radiator. Following a successful install, we then placed our temperature sensors on both the inlet and outlet radiator hose so we could collect road data. Check out the data collection equipment!
