Replace spark plugs every 100,000 miles, no plug wires on Pontiac G6
Problem overview
On the 2.4L 4 cylinder and the 3.6L V6, our technicians tell us that the recommended spark plug life is 100k miles. The ignition coils are mounted directly on top of the spark plugs, as a result there are not longer any spark plug wires to fail.
