I've got the LBZ MP for the swap and was wondering what size coupler I need to join the MP and intake.

4" i.d. It's a little big but you should be able to snug it down fine. I picked mine up at Lowes for like $4 and haven't had any issues with it.

You can order a 4" coupler from a vendor,also if you have a big rig repair/parts they always have in stock its a common part for them
