The A-series engine always gives better performance with a larger piston dish and smaller

chamber volume.

It also means that on an otherwise standard 1275cc cylinder head and engine block the bore size increase can be used initially where required as there are no big problems with compression ratio.

These are totally different to the original Evolution piston stocked pre-2012. Pistons come complete with top quality steel rings, with a three-piece oil control ring.

Minispares’ part number for this item is C-STR311 and it retails at £47.70 inc VAT.
