Our side-mounted Wagner Tuning water coolers are designed to directly replace your vehicle's standard water coolers. By making maximum use of the available installation space, we were able to increase the size of the water coolers by an astonishing 132%.
This significant increase in size, combined with the excellent thermal conductivity of our all-aluminum water radiators, provides significantly improved cooling efficiency. This is particularly suitable for vehicles that are heavily used on the racetrack or that require additional performance modifications. Our complete kit covers both the driver and passenger side and comes with additional brackets to ensure a smooth installation.
Prepare your Audi RS3 8Y for peak performance and optimize its cooling system with our high-quality side engine water coolers.
