Supertech BMW E36 M3 S52/B32 3.2L 87mm Bore -12cc Dish 11:1 CR Pistons - Set of 6 (Excl Rings)

Supertech is known for making well-built engine components, and these pistons for the BMW E36 M3 S52/B32 3.2L are a prime example. If you're rebuilding the heart of your M3, these pistons are designed to handle the demands of a performance engine. They feature an 87mm bore and a -12cc dish, which helps achieve an 11:1 compression ratio when installed in the S52 engine. This compression ratio is a popular choice for a noticeable bump in power without going too extreme for pump gas.

These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for higher performance applications where increased cylinder pressures are expected. The -12cc dish is a specific design feature that contributes to the overall compression ratio, working in conjunction with your cylinder head volume. It's important to note that this set includes six pistons but does not come with piston rings, so you'll need to source those separately to complete the installation.

When undertaking an engine rebuild of this caliber, precision is key. These pistons are made to fit the S52/B32 engine with an 87mm bore. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and torque procedures when installing new engine components.
