How does a spark plug fail?
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.
