93 EX Tune Up
 

Ok so its tune up time. Should i go with all OEM stuff or just grab stuff from auto zone?

Also what parts do i need:

cap
rotor
plugs
wires
pcv valve

optional:
gas filter (looks like it has never been changed)

Any other goodies i might as well get while im at it? Also is there anywhere to get OEM stuff from other than eBay and Honda?
