The spark plug market has seen considerable growth due to a variety of factors.
• The spark plug market has grown strongly in recent years. It will rise from $4.17 billion in 2024 to $4.41 billion in 2025 at a CAGR of 5.8%.
Growth drivers include rising global vehicle production, increased demand for high-performance engines, advancements in engine technology, the adoption of gasoline direct injection engines, and growing automotive production.
The spark plug market is expected to maintain its strong growth trajectory in upcoming years.
• The spark plug market is expected to grow strongly, reaching $5.47 billion by 2029 at a CAGR of 5.5%.
Growth is driven by the shift to electric vehicles reducing traditional spark plug demand, turbocharged engine adoption, electric vehicle growth, automotive aftermarket expansion, and increased production in emerging markets. Trends include improved durability and performance, spark plugs for hybrid/EVs, multi-electrode plugs, iridium/platinum demand, and technological advancements.
The rise in vehicle production is predicted to stimulate the expansion of the spark plug market. This growth in vehicle production is due to a surge in global demand for automobiles, spurred by economic expansion, urbanization, and increased consumer buying power. Spark plugs, vital for initiating and sustaining the operation of gasoline-focused internal combustion engines, are employed to ignite the air-fuel mixture in the engine's combustion chamber. For example, Statistics Canada, a national statistical organization based in Canada, reported in June 2024 that the total count of registered motor vehicles on the road in Canada in 2022 was 26.3 million, representing a marginal increase of 0.3% compared to 2021. Consequently, the rise in vehicle production is fuelling the growth of the spark plug market.
