Hello all, I'm currently working on a 2000 SL. There is a strong idle on my car. The check engine light turned on and the code P0507 popped up on the screen. I know I have to replace the manifold gasket behind the engine. But does anyone have a part number of the gasket like from autozone? Sorry if this has already been asked before I'm kinda new here. Thank you all for the help!

Felpro is fine. wholesaler closeout explains the ridiculously cheap price.

Be advised that although Rock Auto offers a tremendous variety of parts for many vehicles. their shipping costs are often prohibitive on parts like this which weigh nothing but carry the same 8.00 shipping charge as the 1st item on any order.
But in this case, $4 + $8 shipping = $12 frm RockAuto
$19 Amazon w $0 shipping (amazon prime)

I routinely use their site to find part numbers for all kinds of cars. In 22 years I am yet to find a bogus listing. If they don't still carry the OEM part, you can still back the info out of the aftermarket products by seeing what they list as part numbers they replace

google ACDELCO 21009471 and do your homework
