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

BMW keeps setting the benchmark for performance luxury, and the F8X generation is no exception. The S55 powering the 2015-2020 M3, M4 and M2 Competition runs a slick air-to-water intercooling system - but where BMW built a strong foundation, we saw room to push further.
----
The Mishimoto F8X Performance Intercooler Power Pack tackles the weak points, starting with the charge pipes. Factory plastic pipes are notorious for cracking under pressure or splitting at the seams - not what you want mid-corner. Ours are full aluminum with a cast mid-section engineered to snake past the intake, finished with matte black silicone couplers for a sleek, secure connection.
----
Our Performance Air-to-Water Intercooler drops right in and looks the part, available in black or BMW-specific colors so your go-fast parts match your paint. The beauty runs deep: a bar-and-plate core with 29% more volume, a single-pass coolant layout for optimal heat transfer, and 16% more flow - good for a 12°F drop in intake air temps.
----
The heat exchanger got the same treatment. We added 6 inches of core height for a 180% jump in external fin surface area and 60% more volume, netting a 10F drop in coolant temps. Fully assembled on our stage 1 tuned M3, the Power Pack delivered an average gain of 11 whp and 8 wtq. An optional steel mesh stone guard protects the fins, and a variable fin pitch keeps DCT-equipped cars cool under load.
----
The F8X was built to pull ahead of the pack - this is the cooling upgrade that lets it. Like everything we make, the Power Pack is backed by the Mishimoto Lifetime Warranty.

Product Overview

Available in 12 BMW-specific colors, your go-fast parts in the engine bay can now match the exterior beauty of your F8X. The beauty is more than just skin deep too. Our improved core design features a bar-and-plate core with a 29% increase in core volume, as well as a unique single-pass coolant flow layout for optimal heat transfer. Combined with our 16% increase in flow through the core we were able to record a 12°F temperature drop in intake air temperatures while testing our full Power Pack. An air-to-water intercooling system wouldn't be complete without the heat exchanger. When it came to BMW's design, it was a solid foundation, but we still saw room to grow, literally. Our full aluminum design added 6" to the height of the core equating in a 180% increase in external fin surface area, and a 60% increase in core volume. 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.

Mishimoto's charge pipes feature full-aluminum construction with a cast mid-section and matte black silicone couplers that can handle the boost pressure, unlike the factory plastic that can crack under pressure, or split at the seams, creating a less than ideal situation as you pilot your vehicle. Next, the non-descript box is replaced with a stylish, colorful air-to-water intercooler featuring a bar-and-plate core with increased core volume and a single-pass coolant flow layout for optimal heat transfer. Adding to both these improvements is Mishimoto's larger full-aluminum heat exchanger providing increased external fin surface area and core volume.
