I had a friend 3D print an AFM pipe without the AFM in it for when I tuned the car on the Link ecu. Keeps the intake set up looking factory and means you don't have the AFM sitting in the intake doing nothing and looking messy.
Yeah, I wrote one up years ago, just a matter of finding it. But it should be there!
Edit, hah, beaten to it... But no, that's not the guide, I actually did write a tutorial on how to install it.
