Volvo S80 Spark Plugs

Spark plugs are parts of the ignition system, and their main role is to produce sparks that cause explosions of the fuel-and-air mixture in the combustion chambers of the cylinders. Timing and precision are paramount for the adequate and efficient operation of the vehicle. Besides, spark plugs are in charge of absorbing and dispersing part of the huge heat energy produced during combustion. Unfortunately, spark plugs have a relatively short lifespan, and replacing them is one of the most common service practices in every car, including the Volvo S80. Worn or faulty spark plugs result in engine misfiring negatively affecting performance and damaging the cylinders in the long run.

A typical spark plug consists of a nickel alloy electrode designed for delivering the spark and ceramic insulation layer responsible for dispersing part of heat energy. The thickness and geometry of the ceramic layer define the two main families of spark plugs: cold and hot. Cold spark plugs carry a thin ceramic coating to disperse heat quickly and are more suitable for high-performance engines. Hot spark plugs, on the other hand, feature a thick ceramic layer to improve the burning of carbon deposits on their electrodes prolonging their service life. In our online store, we offer a vast assortment of both hot and cold Volvo S80 spark plugs offered at a competitive price.
