The PLM Heat Exchanger XL PLM-MSL55-HEAT-EXCHANGER-XL is designed to handle the extreme heat generated by supercharged Mercedes-Benz SL55 AMG 5.5L engines. This upgraded version is 25% larger than the standard, giving your car the cooling power it needs under intense performance conditions.
With 2.25 liters of fluid capacity and an impressive 4000 in² of fin surface, it’s engineered to reduce intake air temperatures (IAT) and help eliminate heat soak—keeping your power levels consistent when it matters most.
Built from 100% TIG-welded aluminum, and furnace brazed with CNC billet necks, it offers a lightweight, durable, and efficient cooling upgrade that installs without cutting or modification.
