The Alucon 0.75D radius aluminum donuts are ideal for tight spaces in the engine bay. They are perfect for use in areas such as the throttle body to intercooler connection, turbo compressor outlet, and intercooler inlet and outlet. Sold as unwelded sets, these donuts come cleaned and ready-to-weld right out of the package. The surface finish matches the high-quality finish of the Alucon aluminum line of materials.
*Due to the manufacturing process, the aluminum thins slightly in the tight radius area, so it's important to monitor the heat carefully during welding in this section.
