The global spark plug market size was valued at USD 3.69 Billion in 2023. It is projected to reach USD 5.68 Billion by 2032, growing at a CAGR of 4.89% during the forecast period (2024-2032). The increasing production of vehicles worldwide is a primary driver for the spark plug market. As automotive manufacturers produce more cars, the demand for essential components like spark plugs also rises. This trend is particularly evident in emerging economies such as China and India, where the automotive industry is expanding rapidly.
Spark plugs are essential components of an automobile's ignition system. It is intended specifically to ignite the combustion mixture within the engine cylinder. A spark plug ignites the air-fuel mixture at ideal pressure within a closed chamber. Market participants are investing in the development of spark plugs with a longer lifespan and enhanced electrical energy conductivity. With the introduction of next-generation engines, demand for high-performance spark plugs will grow in the future years. According to studies undertaken by the American Physical Society, putting plasma in the area of the region where the flame ignites will result in the production of a catalyst that improves and completes fuel combustion. The replacement of the ignition spark with plasma is a recent trend among spark plug makers, particularly for premium automobile sectors. Companies such as Pulstar Spark Plugs are investigating ways to leverage the potential of plasma-assisted combustion in order to meet the need for the best engine performance. These developments will stimulate market demand.
Due to oil price volatility, the difference between diesel prices and gasoline prices has reduced considerably over the years. It has made consumers shift to gasoline cars. Stringent government norms and regulations regarding emissions have made it difficult for automobile manufacturers to maintain fuel efficiency. Over the past few years, the automotive industry witnessed tremendous growth in emerging economies owing to rapid development and increased investments in the regions. The emerging economies, including Asia-Pacific, Latin America, and Southeast Asia, experienced a high influx of OEM investments to reduce production costs. The geographic diversification of the automakers has created a new manufacturing hub in emerging markets. The expanding automobile industry, notably in China, Brazil, and India, opens potential avenues for the turbocharger market. The Thailand Automotive aftersales Industry underlined that there would be over 18 million passenger cars in Thailand by 2020, thus presenting an attractive opportunity for the spark plug market in the automotive aftermarket arena.
The rise in the urban population and increased consumer incomes are driving the passenger vehicles' demand. Additionally, the easy credit facilities and the increased mobility needs have led to a rise in passenger vehicle sales in these emerging markets. Around 25 million cars were sold in 2018 in India, and the number rose to 26.3 million K Units in 2019, as per the statistics published by the IBEF. The growing middle-class population and changing demographics of millennials are resulting in the strong growth of the passenger cars market, which is anticipated to fuel turbochargers' demand. The China Association of Automobile Manufacturers (CAAM) estimates a rise of 11.1% Y-O-Y growth in passenger cars' retail sales in 2021, with the sales volume reaching 2.14 million K Units. According to recent data published by the International Organization of Motor Vehicle Manufacturers (OICA), production figures are expected to be back on track in the first half of 2021.
It is expected that the EV market is going to make a faster rebound as compared to fuel-powered vehicles post-COVID-19. This is likely to impact the spark plug market as Electric Vehicles do not require spark plugs to function. It is not yet certain how quickly consumers adapt to this transition. The growing sales of electric vehicles can slow down the growth of the global spark plug market.
The development of modern gasoline engines with high mileage and low emissions without sacrificing performance was spurred by the implementation of severe environmental regulations and emission standards to reduce the carbon footprint and combat global warming. These next engines are tiny, necessitating the development of a new type of ignition system and spark plug technology. Market participants are experimenting with different materials and modifying their designs to fit the requirements. The need for spark plugs will be driven by the development of long, slender spark plugs that can be installed in a tiny engine headspace. The introduction of iridium spark plugs that have a longer lifespan, enable superior combustion, and can operate in harsh marine environments will increase market demand. Modern engines operate at increased gas pressure when conventional spark plugs are ineffective. Utilizing spark plugs with plasma assistance in such extreme conditions will increase efficiency. As demand for modern spark plugs continues to rise, fast innovation will drive market expansion.
