A set of six forged pistons, complete with wrist pins and piston rings, engineered as a performance upgrade for the BMW N54B30 twin-turbo inline-6 engine. The pistons are sized at 84mm/84.5mm bore with a 22mm wrist pin and a 10.2:1 compression ratio, and are offered with a Moly or Phosphate skirt coating to reduce friction and improve durability under increased boost loads compared with the factory cast piston.

Fitment: BMW 1 Series and 3 Series, and Z4 models (chassis E82, E90, E92, E89) fitted with the N54B30 twin-turbo engine.
