Description 20V 4age Blacktop – Piston set 81.5mm ( 0.5) Set of 4 x new and oversize pistons at a 81.5mm bore size ( 0.5mm). Also includes the matching Gudgeon pins and retainer clips to suit. – DOES NOT INCLUDE PISTON RINGS – This product is for the pistons set only. See further down for more information. AVAILABILITY NOTICE: Due to a supply issue we are unlikely to once again offer these for sale, however they are now available in an OEM replacement made by Endurotec, these are available through the business Autosurplus on their website To suit piston ring widths – Top: 1.2mm – Middle: 1.5mm – Bottom / Oil control: 3mm Sourcing piston rings – While we do not offer the matching piston rings to suit these oversize 20V pistons it is of note that the 7afe engines use a dimensionally identical and thus directly interchangeable ring set with all of the OEM 20V pistons when matched in diameter. This should make it quite easy to source a local aftermarket alternative. 7afe engines also have the same OEM bore size of 81mm and an 81.5mm / 0.5mm oversize option. – The piston ring sets intended for OEM 16V 4AG pistons ARE NOT COMPATIBLE due to using a different width of oil control / scraper ring.
