I'm about to grab some spark plugs ( 6 NGK Iridium) for my car but I've heard I should change the wires too? What wires are these and where can i grab them?

 

the maxima has a distributeless ignition system it uses individual coil packs rather than a single coil pack that distruputes the ignition through wires to the individual cylinders. You don't need to change any wires just the plugs.

 

so there's no point of getting wires, right? just the spark plugs?

 

4 cylander engines, or engines with a single coil pack get gains from new plug wires...our engine doesnt

 

there are no wires to change...
