what are the gens of honda/acuras?

hay all i've never posted in this section before.

i'm trying to open a online store for performance parts. and to keep the cost down for me i'm going to list the parts in gens. not years.

what i need is the years and gens for all Honda's and Acura's. i'm going to try and get the best parts and the best parts for you. and would like your help. thanks

being an automotive clerk, auto mechanic, and armoured vehicle mechanic, i personally would not like my distributor to not know basic info on the stuff they sell.

PS: same gens does mean all parts will exchange. there are differences within the gens. basically, catergorizing your parts solely based on gens, will not universally apply.
