Machined from 6061 aluminum with a brushed finish, the tube is sized at a 4\" outside diameter and a 0.078\" (2mm) wall thickness, making it easy to trim, join or weld into bespoke piping runs. Whether you're fabricating intercooler piping, an air intake, or patching a charge-air line, this section offers consistent inner flow and corrosion-resistant performance for aftermarket and custom projects.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the key dimensions and material details?\u003c\/h3\u003e\n\u003cp\u003eThe pipe measures 4\" OD (102mm) with an 11.8\" (300mm) overall length and a 0.078\" (2mm) wall thickness.
