With 640 Hp and 900 Nm the new Stage K4 Kit tops the range of Kleemann
performance upgrades for the 5.5 litre V8 AMG Kompressor engine.
The Stage K4 Kit is based on the well known Stage K3 Performance kit
consisting of a bespoke pulley wheel, an ECU upgrade, Super Sport
camshafts, the Kleemann tubular headers and high flow exhaust system
in stainless steel.
To obtain the ultimate increase in power and torque the Stage K4 further
more features a modified inlet house and throttle body.
