Why do my spark plugs keep popping?
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque. Proper installation torque is critical in the plug’s ability to dissipate heat out of the combustion chamber and into the cylinder head.
How tight should spark plugs be tightened?
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench. (Taper seat: About 1/16 turn more.)
What happens if spark plugs aren’t tight enough?

The misfires can also cause problems to the air/fuel mixture that can affect your vehicle’s fuel economy.
How often do you need to change spark plugs?
As a general rule, there are only two times when installing new spark plugs would be necessary; when your vehicle has reached the factory specified service interval, or when your vehicle’s engine Is misfiring or idling poorly, and plug failure is suspected.
What causes a spark plug to wear out?
The tip of each spark plug is exposed to each explosion, which inevitably causes wear over time. Seals and gaskets are often one of the first things to wear out in a vehicle, as they are often made of rubber, plastic, or silicone. If you have a worn O-ring seal, oil can leak onto the tip of the plug, preventing a spark.
What kind of spark plug should I use?
Look for plugs made from iridium or platinum for the longest life (copper has the shortest lifespan – generally about 20,000 miles). Oil Leaks: When you pull a spark plug out of the engine, the base should be relatively clean.
Why are spark plugs important to your car?
