This is a 4-inch (102mm) 90-degree cast aluminum elbow, perfect for custom turbo setups, intercooler piping, or any forced induction project.

It’s made by 1st-Racing and built to handle boost.

The casting is clean, and the aluminum is sturdy—way better than thin-walled tubing that collapses under pressure.

It’s a universal fit, so you might need to trim or weld it depending on your setup.

Outside diameter is about 89mm (3.5 inches) if you’re matching to couplers.

Comes with a 6-month warranty.
Whether you’re fabbing up a new hot side pipe or replacing a crushed bend, this’ll get the air flowing.
Brand new, ready to weld.
