that definitely looks like an LS6 intake manifold.

actually, a painted LS6 intake manifold

according to Pace Parts, the right part # is 88894339 - 2002 ZO6 (LS6) Intake Manifold

Didn't the '02 f-body LS6 intake manifolds have a different part #? I remember a post not too long ago where one of our sponsors noted how that particular manifold outflowed the LS6 slightly.

Yep, the actual "ZO6" intake p/n differs from the '01-up F-body intake.

What you have pictured appears to be legit. It's probably an '01-02 F-car intake.

The black paint looks nice, BTW. I've thought about painting mine black as well.

Thanks GeorgeC. That's what I thought. I didn't want to sound like a jackass so I waited for some back up.

FWIW, this is the part number on mine, too. I was told that part number is an old Canadian part number for the F-car "LS6" manifold that GM replaced with the one that starts with all the eights. Hope this helps.

Pulled this from an older thread:

Z06 12573573
2001-2002 F-car (Z06 looking) 12561184

just do a search for 12561184 and you'll get that thread.
