driverside is odd side and passenger side is the even number wires.
why did you replace the wires, the plugs arent even due till 60k
with secondary air dont bother replacing them unless you have multiple misfires.
otherwise replace one wire and ship it. that way if a coil is bad you save yourself the trouble of not going in twice.
