Mishimoto 15-20 BMW F8X M3/M4 Performance Air-to-Water Intercooler Power Pack - Mineral 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 replace the stock components with a more robust setup, helping to keep intake air temperatures down and your engine running strong. What you get in this kit is a complete package: the main air-to-water intercooler, a larger heat exchanger, and a set of aluminum charge pipes. This means you're getting everything needed to significantly upgrade the cooling system for your S55 engine.

The heart of this system is the improved intercooler core, which boasts a 29% increase in volume and a unique single-pass coolant flow design for better heat transfer. Mishimoto also updated the heat exchanger, making it a full aluminum unit that's 6 inches taller than stock, giving it a 180% increase in external fin surface area. These improvements work together to drop intake air temperatures by up to 12°F and reduce overall intercooler coolant temperatures by 10°F. The kit also includes new aluminum charge pipes, addressing a common weak point in the factory plastic pipes that can crack under pressure. These new pipes are built to handle boost more reliably and connect securely with matte black silicone couplers.

This Power Pack is available in Mineral Gray to match your car's exterior, or one of 11 other BMW-specific colors, so you can customize the look under the hood. Mishimoto backs this kit with their Lifetime Warranty, giving you confidence in its durability and performance for your M3 or M4 build.
