Mishimoto - BMW F8X M2/M3/M4 Performance Air-to-Water Intercooler Power Pack

Mishimoto Performance Intercooler Power Pack for 2015-2020 BMW F8X M3, M4, and M2 Competition (S55)

BMW’s F8X generation M cars—M3, M4, and M2 Competition—are renowned for their precision engineering and track-ready performance. Powered by the advanced S55 twin-turbo inline-6, these machines come equipped with a sophisticated air-to-water intercooling system. While effective from the factory, Mishimoto identified opportunities to elevate the cooling efficiency, durability, and power potential of these vehicles.

The Mishimoto Performance Intercooler Power Pack addresses common weaknesses in the factory system, starting with the notoriously fragile plastic charge pipes prone to cracking or splitting under boost pressure. Mishimoto’s charge pipes boast a durable full aluminum construction with a cast mid-section engineered to clear tight intake areas perfectly. Matte black silicone couplers provide a secure, OEM-quality connection to the intercooler.

Beyond the charge pipes, the upgraded intercooler core features a robust bar-and-plate design with cast aluminum end tanks, offering a 29% increase in core volume and 16% improved flow. The unique single-pass coolant layout optimizes heat transfer, resulting in significant reductions in intake air temperatures for enhanced performance and reliability.

Complementing the intercooler is an all-aluminum heat exchanger with 180% more fin surface area and 60% larger core volume than stock, delivering superior cooling capacity and improved flow thanks to its variable fin pitch. An optional stone guard protects against road debris, preserving longevity on spirited drives or track days.
