Turner Motorsport Stepped Intercooler - F2x F3x 228i 235i 328i 335i 428i 435i

Engines make more power when you're able to move as much air and fuel as possible through them. However, air density is just as important as air volume. Cooler air is denser air, so in addition to keeping your engine cool, it's important to make sure that your intake charge is as cool as possible. Turner Motorsport's upgraded intercooler works to reduce air temperatures with a bare minimum of pressure drop. Less pressure drop means less restriction, and a turbocharger that doesn't have to work as hard. This results not only in a longer service life for your turbocharger, but a substantial increase in performance as well.

The stepped design increases volume and surface are in a limited space by adding an additional smaller core at the top of the intercooler. Both cross sectional area and frontal surface area are increased by a whopping 56%, with a design that still weighs under 20 pounds. On the stock intercooler, the temperature differential between the inlet and outlet sides of the intercooler represented a 95 degree drop. With the Turner Motorsport intercooler, that drop was increased to a chilling 140 degrees. The dyno results don't lie: as a bolt-in upgrade, expect gains of 18 wheel horsepower and 10 lb/ft of torque. With a tune and supporting modifications, further gains are possible, up to 36 horsepower and 28 lb/ft of torque.

This cast aluminum intercooler features an attractive, easy to clean matte black finish, with etched Turner logos on the front and bottom. If you're looking for the ultimate cooling system upgrade for your turbo BMW, look no further.
