Hey guys,

Does anyone know in which years the EGR tube is interchangeable on the C4? Specifically I'd like to know which years will swap out with an 88.

My EGR tube was removed many years ago, and I'm wanting to put it back now. I'm looking at an 89 that has a sensor/wire coming out of it, and I don't remember it being on my original.

In case there's any question, I'm talking about the metal piece that goes between the intake and the exhaust manifold and annoys people who want to remove their passenger side valve cover.

Thanks.

They all physically interchange;I believe your '86 should have the EGR temp switch

Mine's an '88, not an '86. All the same, I thought the '86 needed a crimp on one side.

all 87-91 have the dual flange tube
