Genuine Honda PM6 pistons for many of the D series engines.
The 13101-PM6-010 is listed for engines such as the D16Z2 in applications such as the Civic and Civic Shuttle up to about 1991. From 1992/1993 onwards this part (the items for sale - 13101-PM6-020) is listed for the same D16Z2 engine code.
As quoted on a few websites, 13101-PM6-020 is believed to be a succession part for 13101-PM6-010 and therefore by inference (e.g. from Wikipedia's list of Honda D series engines) they should fit D16A6 engines. Some websites also suggest they fit Honda "ZC" series engines from the same period.
This is all the information I can gather on these items. My intended application was a 1993 car with D16Z2 engine. Please make your own checks and be 100% certain these are the correct items for your intended application, as I'm not accepting returns.
Most if not all websites now show these parts as no longer available.
Full set of 4 brand new and boxed.
NPR piston rings for same, new and boxed (box seal broken to photograph).
Both the pistons and rings are standard size (STD) - not oversized.
Purchased somewhere around 7 to 8 years ago for an engine rebuild that never happened, and have been stored ever since.
