Koyo Air to Water Intercooler Heat Exchanger Upgrade for 2018 BMW 4 Series M4

Koyo's air intake heat exchangers are designed specifically to solve this problem, giving you colder, denser air for increased horsepower and torque. Air-to-water intercooling is the wave of the future when it comes to modern turbocharged vehicles, and Koyo is at the top of the pack in developing high-performance heat exchangers to dissipate heat as quickly as possible and give your BMW 4 Series M4 an added power boost!
