180/200/250CGI (M271 EVO)

The EVO version of the M271 engine is an extremely efficient turbocharged, direct injection engine, powering mid-range models such as the C, E and SLK. All 3 versions of this new engine are 1.8 liters in displacement, but have individual factory ECU programming for different power outputs (180: 156 HP, 200: 184 HP, 250: 204 HP).

Our K-Box (CGI) delivers a performance gain across the entire rev range. Compact and effective, the K-Box is an easy installation with no special tools required.

If you want the most performance possible from your 180/200/250 CGI vehicle, we recommend adding our turbo down pipe with race catalyst, as well as a the performance air filter. These parts are simple bolt ons with modest tools.
