It's time for some new plugs wires and other goodies as my H3 starts to get older. I understand that iridium AC Delco plugs are the go to now with the I5 motor. What I have a question about it plug wires, distributor cap, and rotors everyones using. Anything that improves running quality? I'm new to self servicing these newer aged cars that you can't sit in the engine compartment and tune the car. GO EASY ON ME! haha

 

I moved this from the "no post archive section" to the H3 section where it might be seen and responded to.

Next, your I5 has no plug wires, no distributor, and no rotor. Distributorless ignition coil on plug packs, zero maintenance.

 

you have to be careful with the iridium plugs in the I5s because some of them don't like those plugs and will run a little rough.
