Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
What spark plugs should I purchase for a 1999 Chevy Lumina LTZ
(1) Answer
A/C delco supplies the original spark plugs for your 99 Lumina, the recommend replacement interval is 100,000 miles. My suggestion would be to replace the spark plugs with the same original equipment A/C delco plugs and also change the spark plug wires at the same time. That way your plugs and wires should be good for another 100,000 miles.
