The stock intercoolers are well suited for stock engines, but they weren't designed for four-digit power levels. That's why Mishimoto has developed our performance air-to-water intercoolers for the 2016+ Q50/Q60 3.0T. Our intercoolers feature a 49.8% increase in core volume over the stock intercoolers for improved heat transfer and maximum performance. That increase in core volume, combined with optimized tubes and fins, also allows our intercoolers to be over 51% less restrictive than stock. That means your turbos don't have to work as hard, and the boost pressure they generate isn't wasted shoving air through a restrictive intercooler.
