Mishimoto 2015-2020 BMW F80 M3/M4 Intercooler Frozen Dark Blue II Metallic

When you're pushing your 2015-2020 BMW M4 to its limits, keeping intake air temperatures down is key to maintaining performance. The S55 engine in these cars uses an air-to-water intercooler system, and while BMW's design is good, Mishimoto has identified areas for improvement. This intercooler is designed to address those weaknesses, offering a more robust and efficient cooling solution for your M4.

Mishimoto starts with a larger bar-and-plate core, expanding the volume by 29% compared to stock. This bigger core, combined with a unique single-pass internal fin layout for the coolant, helps transfer heat more effectively from the charged air to the coolant. The end tanks are fully cast aluminum and TIG-welded to the core for solid durability, even when you're running higher boost levels. Internal air diverters in the end tanks ensure that charged air flows evenly through the entire core, maximizing its cooling potential. In testing, this intercooler showed a 16% increase in flow and dropped intake air temperatures by 12°F, with notable horsepower and torque gains.

Beyond the performance improvements, this intercooler is finished in a Frozen Dark Blue II Metallic paint, matched to OEM colors for a sleek look under the hood. Installation is designed to be a direct fit, meaning no modifications are needed to install this upgraded intercooler. It's backed by the Mishimoto Lifetime Warranty, giving you confidence in its long-term performance.
