An automotive spark plug is a component that fits into each cylinder of an internal combustion engine that runs on gasoline and generates an electric spark to ignite the mixture of air and fuel. In order to ensure efficient combustion while the engine is cold, a heating element known as an automobile glow plug is installed in each cylinder of a diesel engine. According to PMR analysis, the steady growth in the automotive industry to spur the market growth for spark and glow plugs during the forecast period.
The automotive spark and glow plugs account for about 1.5-3.5% of its parent market during the estimated year 2025.
The automotive spark and glow plugs observed declining growth during the pandemic period owing to strict lockdowns creating supply chain disruptions in the market. Although, the demand for automotive spark and glow plugs is projected to grow a CAGR of 3.0% to reach a valuation of about US$ 9,197.4 Mn by the end of 2033. Due to the quick increase in use of lightweight vehicles, the demand for the market is projected to grow at a CAGR of about 2.9% during the first half of the forecast period and 3.1% during the second half of the forecast period.
Both new and aftermarket sales are expected to expand significantly as a result of the increasing demand for personal and independent mobility, which will also enhance the market's economics after the pandemic. Automotive spark and glow plug sales for new and aftermarket vehicles will undoubtedly increase due to the anticipated rise in demand for the transportation of heavy commodities.
The market for automotive spark and glow plugs is expected to grow as a result of a number of factors, including rising automobile production and demand for vehicle parts, upcoming stricter emission regulations, and rising consumer demand for vehicles with high fuel efficiency. Additionally, it is anticipated that in the near future, rising demand for high-performance cars and commercial vehicles in emerging nations will hasten market expansion for automotive glow and spark plugs worldwide. Between 2026 and 2033, the automotive spark and glow plug market is projected to grow at a CAGR of 3.0%. By 2033, the market is anticipated to have increased from US$ 7,502.9 Mn in 2026 to US$ 9,197.4 Mn.
Low emissions from the engine are ensured by the spark plug's smooth ignition and efficient fuel combustion. Glow plugs function similarly to reduce exhaust gas pollutants and enhance diesel engine performance. In order to comply with strict emission standards around the world, automakers are anticipated to adopt more advanced automotive spark plugs and glow plugs in the near future.

In order to comply with strict emission standards around the world, automakers are anticipated to adopt more advanced automotive spark plugs and glow plugs in the near future.
Due to the harsh environment they must function in, spark plugs have a limited lifespan. These plugs typically need to be changed on a regular basis since worn-out plugs can result in high fuel consumption from incomplete fuel combustion, poor starting, and sluggish acceleration during high-speed driving. The absence determined the period of time for spark and glow plug replacement. Conventional spark plugs should be replaced, however, every 30,000 to 45,000 miles depending on the vehicle. Since these plugs' replacement intervals are getting shorter thanks to technological advancements, the aftermarket's need for spark and glow plugs is being constrained. Spark plug replacement rates in wealthy countries are higher than in developing countries. This is mostly because people in these areas are unaware of the numerous problems related to the use of spark plugs that are old and worn out.
Consumers, particularly in industrialized nations in Europe and North America, have been motivated by rising environmental awareness and fluctuating fuel prices to choose electric car types such as battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV). The adoption of electric vehicles is being fueled by an increase in urban population, incentives for electric vehicles, falling battery prices, improved transportation infrastructure in emerging and developed nations, and intergovernmental activities for electric vehicles.
“Rising demand for commercial vehicles to boost the market presence in Europe”
Increasing demand for light commercial vehicles and passenger vehicles across the European region is anticipated to surge the market demand for automotive components. The automotive spark and glow plugs market value is projected to grow and account for about 21.8% in the estimated year 2026.
