Supertech 86-91 BMW M50/52 84.5mm Dia 2.0mm Thick (+0.2mm) High Boost Cooper Ring Head Gasket

Supertech is known for making well-built engine components, and this high boost head gasket is a solid example of their work. If you're building a BMW M50 or M52 engine for higher performance, this gasket is designed to handle the increased cylinder pressures. It features a 2.0mm thickness with a 0.2mm overbore to 84.5mm, making it suitable for engines that have been bored out slightly for improved performance.

The key feature here is the copper ring, which creates a very strong seal under high boost conditions. This type of construction is chosen for its ability to withstand extreme temperatures and pressures, helping to prevent leaks and maintain engine integrity when you're pushing your engine hard. It's a well-made component that's built to last in demanding applications.
