Q: How to remove and install spark plugs for the Honda Prelude?
A: Consisting of a metal shell, ceramic insulator, and two electrodes, a spark plug allows electrical current to arc and ignite the air/fuel mixture in the combustion chamber. It is important to note that the heat range of a plug affects its ability to dissipate heat and is therefore crucial for its performance. Normally, spark plugs require replacement after every 20,000-30,000 miles. Therefore, when replacing it should be done when the engine has cooled down; on cleaning around the plug holes; and using a torque wrench to fix the new plug. Finally, examine them and adjust their gaps using a wire gauge.
