2006 Chevrolet Corvette Q&A
2006 Chevrolet Corvette Question: During a spark plug replacement, should the wires & coils be changed?
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. - ProfessorG
In my opinion I would replace the wires. Rarely do I see coil problem with GM products so I would leave them be. - milesauto
I have 132,000+ miles. The problem is intermittent. I checked plug wires and they appear fine. My air filter does need replacing. I replaced the plugs at around 110,000 miles with NKG plugs.
