Dual-Pass Heat Exchanger

The Weistec Engineering 01-113-00728-3 is a dual-pass heat exchanger engineered to enhance intercooling performance in select Mercedes-Benz AMG models. Constructed entirely from aluminum, this component utilizes a dual-pass design, which extends the time coolant spends within the core, allowing for more efficient heat dissipation. This improved cooling is vital for maintaining optimal engine temperatures and performance, especially in high-output M113K and M275/M279 engines. The heat exchanger is specifically designed for a range of M113K-powered Mercedes-Benz vehicles, including the E55 AMG (2003-2006), CLS55 AMG (2006), SL55 AMG, S55 AMG, and CL55 AMG. It is also noted to be compatible with M275 and M279 engines. Vehicle chassis codes mentioned for fitment include R230, W463, W220, W219, W215, and W211. It is important to note that this heat exchanger is designed for supercharged M113K engines and is not intended for naturally aspirated M113 engines. Additionally, while compatible with M275/M279 engines, specific fitment details should always be confirmed, as some sources indicate it "Does NOT Fit" M279 powered vehicles depending on the specific ECS application.
