Set of 4- I have a couple more spare if required for my engine, so these are surplus to requirements. Come with rings, pins and clips are obviously 77mm- spec is on the Accralite site.
These are ~ £160/piston new - you can still buy rings, pins, and circlips if required brand new from accralite (set of rings are cheaper than VW stock ones!)
9.0:1 CR - and proven to outlast stock PY rods
£400ono
