With a compression ratio of 8.3:1 and a dome volume of -1.25, these pistons are optimized for boosted or high-compression engine builds. Wossner pistons are known for their unique PTFE coating on the skirts, which reduces friction and piston rock, leading to quieter operation and increased longevity. The 4032 alloy (T6) allows for tighter piston-to-wall clearance, further enhancing performance and reliability.\n\nThis piston kit is specifically designed for the Mini Cooper 1.6L 16V models from 2002 to 2007, with engine code W11B16A (Supercharged).
