This review is from: AC Delco MR43T AC SPARK PLUG, 8/BOX AC DELCO SPARK PLUGS (Misc.)
These are the same old reliable AC Delco Spark Plugs you trusted ever since you were a teenager in your 69 Camero except the metal parts are made of Stainless Steel so they won't rust in a Marine Enviornment and the threads won't get stuck in the heads when you forget to maintain your engine for years .
