The 2007 Mercedes Slk 350 is a roadster celebrated for its blend of luxury and performance. Under the hood lies the robust M272 V6 engine, a powerplant with untapped potential. For owners seeking to elevate their driving experience, performance tuning offers a compelling path to extract more power and responsiveness from this already capable machine.
One renowned specialist in Mercedes-Benz tuning, Kleemann, provides a comprehensive suite of upgrades for the M272 V6 engine found in the 2007 SLK 350. Their tuning program is structured in stages, allowing for a tailored approach to performance enhancement.
Kleemann Tuning Stages for the 2007 Mercedes SLK 350 (M272 V6):
-
350-K1: ECU Tuning. This entry-level upgrade focuses on optimizing the engine control unit (ECU) software. By recalibrating parameters such as fuel delivery, ignition timing, and boost pressure (if applicable, though the M272 is naturally aspirated), K1 tuning can liberate up to 305 horsepower and 375 Nm (278 lb-ft) of torque. This stage primarily enhances throttle response and mid-range power, resulting in a more dynamic driving feel for your 2007 SLK 350.
-
350-K2: ECU Tuning and Exhaust Upgrade. Building upon the K1 tune, the K2 stage incorporates stainless steel tubular exhaust headers and downpipes with sport catalysts. This modification reduces exhaust backpressure, further improving engine breathing and unlocking additional power. The K2 package can achieve up to 320 horsepower and 390 Nm (289 lb-ft) of torque. Beyond the horsepower gains, expect a more aggressive exhaust note that complements the sporty character of the SLK 350.
-
350-K3: ECU Tuning, Exhaust, and Camshaft Upgrade. The pinnacle of Kleemann’s offerings for the naturally aspirated M272, the K3 stage adds super sport camshafts to the K2 components. Upgraded camshafts alter valve lift and duration, optimizing airflow at higher engine speeds. This comprehensive upgrade can yield up to 340 horsepower and 400 Nm (296 lb-ft) of torque. The K3 stage is designed for enthusiasts seeking maximum performance gains from their 2007 Mercedes SLK 350, delivering a significant boost in top-end power and overall engine responsiveness.
It’s important to note that while Kleemann specifies these potential power figures, real-world results can vary depending on factors such as vehicle condition, fuel quality, and dyno variations. Prospective tuners are encouraged to seek out independent reviews and dyno results from other 2007 Mercedes SLK 350 owners who have opted for these upgrades to manage expectations and ensure satisfaction with the investment in performance enhancements. The exhaust headers mentioned in these packages are also compatible with other Mercedes-Benz models including SLK R171/W&X, C&GLK W204, C W203 4Matic, E W211/ CLS W219/ SL R230, for both left-hand drive (LHD) and right-hand drive (RHD) configurations.
