With our heat exchanger in the S55’s system we recorded a 10 degree F drop in global intercooler coolant temperatures, and an average gain of 11 whp and 8 wtq when the full Mishimoto 2015-2020 BMW F8X Performance Intercooler Power Pack was tested on our stage 1 tuned M3. For added security, we made sure to include our optional steel mesh stone guard with the Mishimoto Performance Heat exchanger to keep all of the tubes and fins intact. We also utilized a variable fin pitch on our heat exchanger’s core for optimal cooling on DCT equipped vehicles. Where the F8X generation of the M3, M4 and M2 Competition were designed to pull ahead of the rest, there were still somethings that were left to be desired in terms on intercooling. The Mishimoto 2015-2020 BMW F8X M3/M4 Performance Intercooler Power Pack is the perfect companion for your build, and like all of our products, is covered under the Mishimoto Lifetime Warranty.
