034Motorsport Radiator Upgrade Audi S4/S5, RS4e, B9/B9.5 A/RS5 & C8 S6/S7

Product Description:

If you’re looking for a high-capacity, all-aluminum radiator for your EA839 2.9TT or 3.0T equipped Audi, the 034Motorsport Radiator Upgrade is for you! High-performance driving, especially with added power, can push your engine to generate excessive heat that the factory main radiator may struggle to dissipate. This can lead to elevated coolant temperatures, reducing the effectiveness of your vehicle’s cooling system and potentially impacting performance.

The 034Motorsport Radiator Upgrade is designed to replace your factory radiator with a larger, all-aluminum radiator, engineered in collaboration with the cooling experts at CSF Radiators. The 034Motorsport Radiator Upgrade utilizes an all-aluminum construction, engineered to be a drop-in replacement for the factory radiator. Featuring a thicker performance radiator core and re-engineered billet aluminum end tanks to improve the efficiency of coolant flow, the 034Motorsport Radiator Upgrade increases the coolant capacity by 40% and increases the overall cooling capacity by 16% as a result!

Not only is it larger, but the 034Motorsport Radiator Upgrade utilizes 65 individual 2-row B-tube technology cooling tubes that carry coolant across the radiator core to help disperse heat, significantly reducing recovery time between pulls! CSF’s “B-tubes” are carefully formed and seam-brazed for a stronger, more efficient design than traditional welded “O” tubes. This allows for thinner, lighter aluminum with improved cooling. The seam-brazed inlet increases heat transfer surface area by ~15%, delivering the efficiency of two smaller tubes within the same space.

Additional Cooling Upgrades for B9/B9.5 Audi S4/S5:

When looking to further improve the cooling performance of your Audi B9 S4/S5, consider pairing the 034Motorsport Radiator Upgrade with the Auxiliary Radiator Upgrade Kit, which replaces the factory side-mounted radiator with an upgraded unit from CSF Radiators!
