Not a guru on cars, but I am changing out the spark plugs on my 08 Milan. Should I change the wires as well? If so is this a more "simple" task to do? And, can I get directions on how to do it?
Also, anything I can do as a "do it yourself" job at the 100,000 mile mark on my vehicle for now?

Thanks!

You have the coil on plug setup so you have to remove the coil first and the plug wire. If the plug boot breaks or cracks then replace it. Make sure to gap plugs correctly contrary to what the auto parts guy tells you they are not set from the factory. Replace your air and fuel filters as well.

So, should I be replacing the wires or no? I know I have the coil setup, Is this hard to replace the wires? You mentioned if a plug boot breaks or cracks, is this common when changing out wires? I have the K&N Filter so I believe I can just wash that. Thanks for the heads up on the fuel filter

It looks like pic so if it's bad you replace the whole coil which run anywhere from $60-80 at parts stores.

I'm not sure if other members have access but the statement made on gapping the plugs is incorrect. I purchased Bosch platinum +4 and these require NO GAPPING. While you may need to gap some plugs NOT ALL need gapping especially now a days.
