The Aeroflow Performance tight radius cast aluminium 90 degree elbow is perfect for those who wish to weld an extension on to a turbocharger compressor housing. The compact design is great for creating tight bend turns in the pipework for clearance in tight engine bays with large turbochargers. It is also designed to work with other cast aluminium components such as intercoolers. The extra lip helps to keep your silicone secured. All Cast elbows have a 3mm (1/8") wall thickness.
