Spark Plug Market to Reach $14.7 Billion, Globally, by 2034 at 6.4% CAGR: Allied Market Research

The spark plug market is driven by the rising demand for fuel-efficient and high-performance vehicles, coupled with stricter emission regulations that require advanced ignition technologies. Increasing production and sales of gasoline-powered passenger cars and two-wheelers, especially in emerging economies, further boost market growth. The growing adoption of advanced materials like iridium and platinum enhances durability and efficiency, attracting automakers and consumers alike.

PORTLAND, Ore., Oct. 28, 2025 /PRNewswire/ -- Allied Market Research published a report, titled, "Spark Plug Market by Type (Hot Spark Plug and Cold Spark Plug), Material (Copper, Platinum, Iridium, and Others), End-Use (Automotive, Marine, and Others), and Sales Channel (Original Equipment Manufacturer and Aftermarket): Global Opportunity Analysis and Industry Forecast, 2025-2034". According to the report, the spark plug market was valued at $8 billion in 2024 and is estimated to reach $14.7 billion by 2034, growing at a CAGR of 6.4% from 2025 to 2034.

Rising vehicle production and ownership, especially in Asia-Pacific, along with stricter emission norms, are fueling demand for advanced spark plugs made with durable materials like iridium and platinum. These innovations not only improve fuel efficiency but also extend product life, making them attractive to both automakers and consumers. At the same time, the growing adoption of electric vehicles poses a challenge, as they don't require spark plugs. However, the vast existing fleet of internal combustion engine vehicles and ongoing replacement demand in the aftermarket continue to create steady opportunities for the market.
