Description Keep your gears cool with the Mishimoto 2015-2020 BMW DCT Transmission Cooler. The F80 platform is one that demands peak performance, and the dual-clutch transmission equipped on your M2 Competition, M3, or M4 provides you with lightning-fast precision gear changes putting you in a league above the rest. Extreme heat being applied to your transmission, however, can easily knock your M down a few pegs. Our transmission cooler aims to provide your M with the cooling to keep up on the street and track. We started from the ground up for our DCT cooler design, equipping it with a new 1.25” thick core resulting in a 42% increase in core volume and 69% bump in external fin surface area. The improvements are more than just skin deep too, as we updated this core with a dual-pass flow and internal fins for improved heat transfer. Combined, our upgraded features improve the heat rejection characteristics for better heat regulation of the DCT in your M2 Competition, M3, or M4. The Mishimoto 2015-2020 BMW DCT Transmission Cooler is available in a silver powder coat finish and is covered by the Mishimoto Lifetime warranty for a worry-free installation.
