If you're going to use one of our billet intake flanges, this tubing is a good way make runners. The 1 3/4" ID Aluminum runner tube has an 1/8" wall thickness (2" OD) and is 6061 alloy.

This tube ovals nicely to the right size for most of our billet flanges, confirm before ordering if you're not sure.

Runner Tubing is sold between 2 and 10 inch pieces. select the length you will need for your tubing and choose if you need it ovaled or not then up the quantity going to your cart to select the amount of pieces you need. 

We can also oval the ends. They're done separately, at an additional charge. If you have 4 tubes, you'll probably want 4 oval ends.

The pictures show the tubing with one end ovaled, this is not how they come unless you order ovaling! They will be straight tubes!
