A tune-up kit is composed of several parts, and one of which is the spark plug. This is an indispensable part in your Mitsubishi Eclipse 1989-1999. Two important functions are being performed by the spark plug. First is to ignite the air-fuel mixture and second is to remove heat out of the combustion chamber. Spark plugs transmit electrical energy that turns fuel into working energy so that your Mitsubishi Eclipse can run. The location of the spark plugs makes them vulnerable to extreme temperature variations, chemicals, fuels, and oils. Cylinder pressure produced by the piston and cam timing is also extended into the spark plug. With all these forces, the spark plugs also tend to wear out. Maintenance must be properly observed so that the plugs can perform in their maximum efficiency. Examining the plugs’ color, gap, and any deposit will give you an idea on how your engine performs, as well as the possible engine deficiencies. A spark plug replacement must conform to the manufacturer’s recommendation for optimum use. Look no further and turn to the Nology Spark Plug for your replacement need.
