Okay, I have a 2007 automatic crossfire. I am at 81,000 miles and I am going to be changing the spark plugs. While I am at it should I also change the wires. Or if I am not having any problems should I leave the wires alone. Back in the old days (50 years ago as part of a tune up you changed the wires, coil and plugs. Is that not the case now (minus the coils---no problems there). Back to my question should I change the wires as a matter of course or leave them alone if I am not experiencing any engine problems.

The same question goes for the engine filter, which I have never changed.

What all should I do to tune everything up along with my spark plug replacement (I realize from all of the reading I have been doing that the crossfires do not need tuneups per se). So, I guess at my mileage what would you guys be changing as a matter of general maintenance

Thank you
