ONE SIZE SPARK PLUG DOES NOT FIT ALL

NGK says it has done the hard work for you when it comes to choosing the correct spark plug

While many spark plug suppliers recommend a single part number for a variety of vehicles, NGK says this “one size fits all” approach compromises performance.

“Any manufacturer who still believes they can produce a spark plug to suit multiple applications is living in the dark ages,” NGK Spark Plug Australia Senior Product Manager, James Filshie, said.

“This old school type of thinking disregards advancements in modern engine evolution and can compromise precision engine output, reliability, and fuel efficiency.”

Engine manufacturers spend many years researching and developing a new engine design. During this complex process, every engine component, including the spark plug, is engineered and tailored to perfectly match the make and model.

“Being the largest OE spark plug supplier in the world means that we work hand-in-hand with vehicle manufacturers during the development of each new engine configuration,” James said.

“We engineer spark plugs specifically designed to suit each engine’s individual requirements to ensure optimum performance.”

When spark plugs are generic, important attributes are often compromised and this can have a big effect on performance and longevity, says NGK.

“Our research has found that installing a spark plug that is not specifically designed for the engine in which it is being installed can result in some pretty serious side effects, the biggest of which is the heat range,” James said.

“If the spark plug is too cold then carbon fouling can become a problem, while if the spark plug is too hot, pre-ignition can occur that can cause serious engine damage.”

In addition to heat range, there are a number of attributes which can impact the vehicle when a spark plug is commonised: Centre Electrode Projection length, number of ground electrodes, ground electrode design and Double Fine Electrode (DFE) design.

“To assist mechanics and automotive technicians to quickly and easily identify common spark plug issues, we have developed a series of short videos that you can check out on our website,” James said.

“At NGK Spark Plugs Australia, we are engine ignition specialists. We partner with OE engine manufacturers to ensure all NGK Spark Plugs meet exacting engine specific requirements.” For more information, visit www.ngk.com.au
