so i have a 94 cx hatch with a d16z6 swap and i am going to do the smog next week and i wanted to get new spark plugs..so my question is wat are some good plugs that will help me pass the smog..and do i need to gap them a specific gap to pass or are they already gapped? thanx

 

Go OEM. Most hondas don't like other plugs. NGK plugs are reliable and there is no need to regap

 

Well the OE plugs are NGK
Honda part# is 98079-5514G $3 ea
or go to AZ, Advance or, O'Reilly's and ask for
NGK SPARK PLUG (ZFR5F-11) (NGK) $2 ea
or a one step colder plug is
NGK SPARK PLUG (ZFR4F-11) (NGK) $2 ea

 

you could go 6's if you wanted

 

which plug would be the best to help me on my smog test??
