LS1 intakes have an egr port right behind where the tb bolts up, LS6 intakes do not.

^^LS1 corvette intakes do not have EGR either, so it's best to grab the P/N as well.

Yep, I didn't realize until I helped my friend change his oil pressure sending unit on his 98 and then another on a 99 vette

P/N is the best way and then the flat bottom. There is a sticky somewhere on here about it.

The Stock 2001-2002 F-body LS6 intake is 12561184.

The Z06 LS6 intake is 12573572.

The part number is stamped on top of the manifold, should be on the driverside.

This is probably a stupid question but is there any difference in the 2? Will the Z06 intake work on a 98-00 F-body?

As far as I can tell, there is no difference in performance between the Z06 and the standard LS6 intake. Unless you feel that paying the "corvette tax" for a Z06 intake is worth it, don't bother.

And yes, the LS6 intake will do wonders for a 98-00 car. You have some coolant line issues, but that is easily taken care of. You can either buy the correct coolant lines (ones for 01-02) or just take a chisel and knock off the reinforcing "fins" on the bottom. I prefer the chisel method, as I am a cheap sob.
