Technical detail: Cooling circuit optimization for the M 133 turbo engine The 2.0L M 133 turbo engine in models such as the AMG A 45 (W176) uses an indirect intercooler circuit that employs a separate cooling water circuit to cool the charge air. Lowering the cooling water temperature is the key to increasing performance. The Wagner Tuning side water cooler solves this bottleneck: The 77% increase in volume (3.15 liters vs. OEM 1.79 liters) massively increases the amount of coolant and cooling capacity. The result is more stable system thermodynamics over a longer period of time, which sustainably improves the performance and reliability of your vehicle, especially at high speeds and on the racetrack. Technical data in direct comparison (OEM vs. Wagner Tuning side cooler) The Wagner Tuning side water cooler offers decisive advantages over the standard cooler: Volume: With 3.15 liters, the Wagner Tuning cooler offers 77% more volume compared to the OEM cooler with 1.79 liters. Dimensions (depth): At 68 mm deep, the coolers are significantly thicker than the standard coolers at 40 mm, which enables increased cooling performance. Cooling surface: The cooling surface (A) increases by approx. 4% to 464 cm² (vs. OEM 446 cm²). Cooler core: A high-performance competition racing intercooler core is used. Dimensions of OEM side radiator: 248 mm x 180 mm x 40 mm V = 1.79 liters A = 446 cm² Dimensions of Wagner Tuning side radiator: 252 mm x 184 mm x 68 mm V = 3.15 liters A = 464 cm² Vehicle compatibility (AMG M 133) The Wagner Tuning Competition side water cooler is plug-and-play compatible with the following models with the M 133 engine (265-280 kW / 360-381 hp): Mercedes Benz A 45 AMG W176 (2013-2018) Mercedes Benz CLA 45 AMG C117 (2013-2018) Mercedes Benz GLA 45 AMG X156 (2014-2019) Part number: 400001006 Get ready to dominate the roads and take your driving experience to a new level – now with parts certification!
