How to Buy Good Quality Spark Plugs

Sparks make everything happen! Without spark plugs, your vehicle would never be able to kick off combustion, providing the necessary power to make your car go forward. If your engine is starting to misbehave, by either stalling, lurching, or hesitating then it’s time to start looking at a new set of spark plugs.

When spark plugs falter and fail, it causes a “misfire” – meaning that the engine “skipped” or jumped, which can cause vibrations that can be felt all over the car.

Really important facts to keep in mind:

  • Durability: Durability is important, because it tells you how long that your spark plug will last before you have to get a new set.

  • Fit: Fit provides you with the positive installation experience that you expect. While parts can be aftermarket, it is best to get OEM, new parts for your spark plugs.

  • Spark plug material: Do you want copper, platinum, or iridium spark plugs? All three metals have specific benefits including astronomically high melting points - up to 4,229 degrees F for Iridium, with copper clocking in at 1,983 degrees F. The lifespan of iridium is much longer as well. Why doesn’t everyone want their spark plugs made out of this wonder material? Well, probably because it’s expensive and their vehicle may not accept iridium spark plugs, depending on when it was manufactured.
