Don't have a dog in this fight but looking up the MB 2004 SLK32 AMG TB gasket ( 2004 MERCEDES-BENZ SLK32 AMG 3.2L V6 Supercharged Throttle Body Gasket | RockAuto )? Isn't this the same gasket as the one used for the 74mm TB mod on the N/A? It also seems the one from needswings is also incorporating a 'spacer' integral into its design.
