Mishimoto 2015+ BMW F8X M3/M4 Performance Heat Exchanger

This is the Mishimoto Performance Heat Exchanger for your 2015-2020 BMW M3 or M4. The S55 engine in these cars makes a lot of power, and while the stock intercooling system is pretty good, Mishimoto found ways to make it even better. This part is crucial because it helps dissipate the heat from the charged air that the intercooler transfers, keeping your engine running cooler and more efficiently.

Mishimoto built this heat exchanger to be tough and effective. They ditched the plastic end tanks and ports, using durable aluminum instead. The core itself is a dual-pass design for maximum cooling, and they've significantly increased its size. With a 42mm thick core, a 150mm taller design, this unit offers a 60-percent increase in core volume and a massive 180-percent boost in external fin surface area compared to stock. All these improvements result in an average drop of 9 degrees Fahrenheit in intercooler coolant temperatures, which is a notable gain for keeping your engine performing at its best, especially under demanding conditions. Because this heat exchanger sits right at the front of the car, it's exposed to road debris. To protect the fins, Mishimoto includes a strong steel mesh stone guard. They also incorporated a variable fin pitch on the lower rows, which helps with cooling for models equipped with a DCT transmission.

This heat exchanger is designed to fit right into your F8X M3 or M4, replacing the factory unit. It's a solid upgrade for anyone looking to get the most out of their performance BMW. Mishimoto backs this part with their Lifetime Warranty, so you can install it with confidence.
