Spark Plugs

Spark plugs have been around for decades. They work basically the same today as they did 50 years ago. Nowadays there are so many choices and different configurations on the market  that a lot of people don’t know what kind of plug to choose.
In my opinion the choice is simple. Use the spark plug the manufacturer installs at the factory.  Install new spark plugs when it is recommened by the factory.  This is one of the few services I do recommend doing when the manufacturer recommends. The ignition system and engine in your vehicle are designed around the spark plug. The type of material the plug is made from, the gap and how the spark plug wears are all factors the manufactures take into consideration.
 By changing from a conventional plug to platinum plug you are changing the ignition system and how it works. The same is true if you go from platinum to iridium spark plugs.
 I cannot tell you how many times I have seen a customer come in with misfires and hard starting and it came back to the spark plugs that were just installed. More often than not, some fancy multi pronged platinum with a groove in the tip.
On some long life spark plugs it is a good idea to remove the spark plugs on occasion and perform a spark plug thread service. Basically you clean and lubricate the threads to prevent seizing.
