Supertech BMW M50/M52/B25 85.5mm Dia 2.0mm Thick (+0.2mm High Boost Cooper Ring Head Gasket

Supertech is known for making well-built engine components, and this head gasket is a solid option for BMW M50, M52, and B25 engines. If you're rebuilding the top end of one of these popular BMW inline-sixes, a new head gasket is a critical part to ensure a good seal between your cylinder head and engine block. This gasket is designed with an 85.5mm bore diameter and a 2.0mm thickness, which is a common size for these engines.

What sets this gasket apart is the inclusion of a high boost cooper ring, specifically a +0.2mm one. This cooper ring is designed to provide an extra sealing surface in the combustion chamber area, which can be beneficial for engines that see higher boost pressures or are tuned for more performance. The 2.0mm thickness is a standard dimension, but the cooper ring adds a layer of sealing confidence for demanding applications. It's a well-made component that aims to keep your engine running smoothly and reliably.
