06 corvette coupe.
During a spark plug replacement, should the wires & coils be changed? on 2006 Chevrolet Corvette
Some will say yes and some will say no. Are they giving problems, then yes, very high mileage, yes. Under 100,000 should be OK.
In my opinion I would replace the wires. Rarely do I see coil problem with GM products so I would leave them be.
