Supertech BMW/Mini B48 2.0L 82mm Bore 10.2:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is known for making well-built internal engine components, and these forged pistons for the BMW/Mini B48 2.0L engine are a prime example. If you're looking to rebuild or upgrade the heart of your B48-powered vehicle, this set of four pistons is designed to handle increased stress and performance demands. They feature an 82mm bore and a 10.2:1 compression ratio, which is a common target for builds seeking a balance between power and drivability.

These pistons are forged from high-strength aluminum alloy, a process that creates a denser, more durable structure compared to cast pistons. This makes them significantly more resistant to detonation and mechanical stress, which is crucial when pushing an engine beyond its stock limits. The 10.2:1 compression ratio is a notable increase over stock, designed to extract more energy from each combustion cycle, leading to improved power output. It's important to note that this set does not include piston rings, so you'll need to source those separately to complete the installation.

When installing these pistons, ensure you consult your vehicle's service manual or a trusted professional for the correct procedures. Proper installation, including ring gap setting and cylinder wall preparation, is critical for the longevity and performance of these components. This set is a solid option for enthusiasts looking to build a more robust and powerful engine for their BMW or Mini.
