AIRTEC Motorsport Chargecooler Radiator Upgrade for BMW M2 Comp, M3 & M4 (S55 Engine) AIRTEC HQ in the UK, we’re proud to launch our front mount chargecooler radiator upgrade aimed at BMW M2 Competition/M3 & M4 models for fast road or track use. As the performance of chargecooled-engines depends on the temperature of the coolant inside the system, it’s very important to ensure it runs as cool as possible for as long as possible. As the standard system can struggle to maintain temperature, especially on a tuned application, the keys to ensuring a consistently lower running temperature are to increase the capacity of the system and its ability to cool it. AIRTEC Motorsport’s solution to improving the original set up is utilise the available space behind the front bumper and develop a chargecooler radiator that measures nearly 100mm taller and 20mm thicker overall. This means capacity is increased by a huge 5.4 litres over standard, which is over double the capacity of the original. Frontal area is also increased by 40% to help cool the extra capacity. Despite the huge increases that will allow the chargecooler system to run cooler for longer, the radiator fits neatly behind the bumper and requires no modifications to fit, using the OEM mounts and the original coolant connectors. To protect the larger core in its vulnerable position at the front of the car, there is also a (removable) stone guard. Finished in a high-quality powder-coated black finish, the comprehensive fitting kit includes all fixtures and a detailed instruction fitting guide. The larger radiator can be used with the original chargecooler to improve running temperatures, or to see the biggest performance gains, it’s advisable to use the radiator in conjunction with our ‘Ultimate Specification’ billet chargecooler upgrade: AIRTEC Motorsport Billet Chargecooler Upgrade for BMW S55 (M2 Competition, M3 and M4) Dimensions: OEM chargecooler radiator: Width: 590mm Width: 308mm Depth: 25mm Capacity: 4.5 litres Front area: 181cm² AIRTEC Motorsport chargecooler radiator: Width: 540mm Height: 410mm Depth: 45mm Capacity: 9.9 litres Frontal area: 221cm² Features:  Over twice the capacity of the original 40% larger frontal surface area Twin-pass design for improved cooling Direct fit with no cutting or trimming Removeable stone guard to protect the core Comprehensive fitting guide AIRTEC part no: ATRADBMW1

TECHNICAL DATA As part of our expanding Audi/VW and Seat product ranges, AIRTEC Motorsport are proud to launch our uprated auxiliary radiators for DSG or engine coolant suitable for track or fast road use. The IssueDuring extended periods of track or fast road use, particularly for cars with increased power, both the DSG transmission’s oil and the engine’s coolant can reach temperatures that are too high to offer sufficient cooling protection properties. As a result, there is risk of damaging the transmission and/or engine, so the car’s ECU will automatically limit the engine’s torque output and extend the gearbox’s shift times, which makes it feel notably less responsive and eager. It can even cause permanent damage, if it persistently overheats. The SolutionAIRTEC Motorsport’s solution to improving the DSG’s and engine’s running temperatures is to increase the size, capacity and ability of the original auxiliary radiators mounted behind either side of the bumper. By utilising the available space, we developed a replacement radiator that’s wider and thicker. This means capacity is increased by a huge 67% over standard, whilst frontal area is also increased to help sufficiently cool the extra capacity. The core also features a quadruple pass design, which forces coolant entering it to pass up and down the core four times before it exits, increasing the time the coolant passes through the radiator to further decrease temperatures. The result is a radiator that is able to keep cooler for longer, therefore helping the car run at its optimum for longer. Despite the increases, the radiators fit neatly behind the bumper and requires only minor trimming of the original air duct to fit, otherwise using the OEM mounts and the original coolant connectors. To protect the larger radiator core from road debris, there is also a (removable) stone guard. Finished in a high-quality powder-coated black finish, the fitting kit includes all fixtures and a detailed instruction fitting guide.
