AC Delco 41-932 plus and wires
On 11/29/2003, my dad and I changed the spark plugs and wires on my car. I am now running on AC Delco 41-932 plugs which are rated as one heat range colder plug. I also installed a new set of AC Delco Plug wires. I can tell that the car accelerates smoother and seems to run a little better. It also helps reduce KR (Knock Retard).
