about us

The spark plug generates the electric spark that the engine needs to ignite. They ignite the fuel-air mixture in the combustion chamber and enable the engine to burn fuel smoothly. They can also withstand the extreme temperatures inside the engine, and can burn off any pollutants and particles that enter the combustion chamber from the fuel system, so that they can work at an optimal temperature.

The spark plug works by generating a current between two electrodes, which sparks between the electrode and the housing at the tip of the spark plug. Generally, when the engine is "ignited", the spark plug generates a voltage of about 20,000 volts.Engine Piston Manufacturers

How to check and replace spark plugs
Although spark plugs are very durable and can withstand extreme temperatures and conditions for thousands of miles, spark plugs do require regular inspections to ensure they continue to work effectively. Daily wear and accumulation of deposits can cause spark plug problems, including pre-ignition (spark plug ignition too early) and premature wear, so it is best to know how to check its condition and performance.
