Mishimoto 15-20 BMW F8X M3/M4 Performance Air-to-Water Intercooler Power Pack - Lime Rock Gray

When you're looking to get the most out of your 2015-2020 BMW M3 or M4, especially if you've tuned the engine, the factory intercooling system can become a bottleneck. This Mishimoto Performance Intercooler Power Pack is designed to address those limitations, giving you a more robust and efficient way to cool the air charge. What you get in this kit is the Mishimoto Performance Air-to-Water Intercooler itself, a larger and more effective Heat Exchanger, and a set of aluminum Charge Pipes to replace the factory plastic ones that can crack under pressure.

The heart of this system is the improved intercooler core, which features a bar-and-plate design with 29% more volume than stock. This, combined with a unique single-pass coolant flow, helps transfer heat away more effectively. Mishimoto also updated the heat exchanger, making it a full aluminum design that's 6 inches taller than the factory unit, giving it a massive 180% increase in external fin surface area. This means it can dissipate heat much better, leading to a significant drop in overall intercooler coolant temperatures. The kit also includes new aluminum charge pipes, which are a common failure point on these cars, ensuring a solid connection and better boost handling. When tested on a Stage 1 tuned M3, this full power pack resulted in an average gain of 11 horsepower and 8 lb-ft of torque, along with notable drops in intake air and coolant temperatures.

This kit is available in Lime Rock Gray, matching many BMW exterior colors, or classic black, allowing you to customize the look of your engine bay. Mishimoto also includes a steel mesh stone guard with the heat exchanger to protect its delicate fins and tubes from road debris. Like all Mishimoto products, this intercooler power pack is covered by their Lifetime Warranty, giving you peace of mind with your investment.
