This gasket worked great! Perfect fit and alignment. I have replaced my C4 pan gasket several times with the cork/rubber gasket and even a paper gasket but it kept "weeping" fluid. Since I have installed the Moroso Perm-Align gasket the weeping/seepage has stopped. I applied gasket adhesive to the "pan" side of the gasket, let it set up, and no more leaking. This should make it much easier when I change the filter. This was the part I needed.
