What drives the price
Genuine, OEM supplier, aftermarket
Genuine engine gaskets and seals carry the marque box and the marque price. On sealing surfaces that get one shot — head, timing cover, oil filter housing — that box is worth it.
Most of those genuine parts leave the same plant as the OEM-supplier part. Elring, Victor Reinz, Febi, Corteco. Same rubber, same steel carrier, no roundel on the box, usually a third less.
Aftermarket is fine on mounts, pans, and hardware where fit is mechanical and failure is loud, not silent. It is not fine on a gasket buried behind eight hours of labor. Labor sets the rule here, not price.
