EGR thread sizes!!!

[Bvisailer]

At home depot now and can't figure out what proper sizes I need to install a flexible line for when I install the thermal spacer. Anyone know off the top of there head what the sizes are?

I believe the exhaust side was 1/2" and the intake is a little bigger, never did the intake side though so I couldnt say for sure

Alright. And I'm guessing by the looks of them there fine thread? I may just end up taking stock pipe to a plumbing store and see what they can come up with.

Well its a NPT. 1/2" FPT would be the cap for the exhaust side and unsure of the intake side like I said. I got mine at lowes but it was a while ago so Im not 100% positive on the size

The bung on the header is 1/2" flare thread, but the stock tubing is larger than what would normally be used with a 1/2" fitting.

1/2" soft copper tubing can be used in place of the stock EGR tube, and is somewhat flexible.
