I got some 10.4mm plug wires they said they were for a eg or ek civic I put them on on ef and they make it misfire has anyone else had eg or ek wires on a ef that ran good? It only seems to do it if the motors warm but runs find when cold

 

Never had this problem. If they are for the same series of motor, they should work. I used my B series DOHC NGK blues on a D15 with no issues.
