EA839 2.9TT/3.0T All-Aluminum Radiator Upgrade

The 034Motorsport Radiator Upgrade is a high-capacity, all-aluminum replacement for the factory radiator in EA839 2.9TT or 3.0T equipped Audis. The factory radiator can struggle to dissipate this heat, leading to elevated coolant temperatures, reduced cooling system effectiveness, and potential performance impacts. This upgrade ensures improved coolant capacity and seamless integration with your vehicle’s existing cooling system. Constructed from all-aluminum with 100% Tig Welded seams, the radiator features billet aluminum end tanks with machined inlet and outlet provisions. It boasts a thicker performance radiator core (42mm vs. OEM 35mm) and utilizes 65 individual 2-row B-tube technology cooling tubes with a 5mm fin height. These B-tubes, a CSF innovation, are carefully formed and seam-brazed for enhanced strength and efficiency compared to traditional O-tubes, allowing for thinner, lighter aluminum with improved cooling. The seam-brazed inlet increases heat transfer surface area, delivering the efficiency of two smaller tubes in the same space. This upgrade provides a significant increase in cooling performance, offering a 40% increase in radiator coolant capacity (3.5L vs. OEM 2.5L) and a 16% increase in overall cooling capacity. It is engineered as a direct, drop-in installation, compatible with OEM accessories, ensuring a straightforward replacement of the factory radiator. For those looking to further enhance their Audi's cooling system, 034Motorsport also offers an Auxiliary Radiator Upgrade Kit, which replaces the factory side-mounted radiator with an upgraded unit from CSF Radiators.
