Anyone know the difference between the 92 L67 EGR and the 93 L27 EGR? I thought they were the same, but ACDelco.com lists different part numbers.

I know there is different types of EGR'* on the Bonne'* as for years I'm not sure. I think the difference is one digital one is not. As for a performance gain in changing? I dought that it would make a difference.

They are both digital. I was looking at swapping one from a 93 SE to my 92 SSE because mine is not working properly.

As far as I know, the digital EGR valve is the same for the '92 and '93 but the mounting base and pipe to the exhaust manifold are different. I own a '92 and a '93, and they look the same until you look at them closely.

By the way, if anyone has the EGR pipe and mounting base for a '92 L67 for sale, I need one.
