Spark Plug Sales Set to Total USD 21,353.5 Million by 2034 Amid Rising Demand for Enhanced Engine Performance | Future Market Insights, Inc.

The rise of electric vehicles (EVs) and hybrid powertrains is reshaping the automotive aftermarket for spark plugs. Spark plugs market growth is attributed to increasing development in the automotive industry with regular usage of vehicles globally, particularly in emerging markets. Similarly, regular maintenance and replacement cycles in these vehicles further drive the spark plug aftermarket growth


NEWARK, Del, July 18, 2024 (GLOBE NEWSWIRE) -- The global spark plug market size is anticipated to be valued at USD 1, 1887.3 million in 2024. Global sales of spark plugs are set to total USD 21,353.5 million by 2034. The market is anticipated to witness a CAGR of 6% from 2024 to 2034.

The primary function of spark plugs in internal combustion engines is to ignite the air-fuel mixture within the engine's combustion chamber. The type of material used determines the operational ability of these igniters. Hot spark plugs are durable, reducing costs and increasing their lifecycle.

Iridium material is preferred due to its exceptional durability and performance, with a longer lifespan compared to copper spark plugs. They can withstand high temperatures and electrical stresses, and their thermo-edge design facilitates anti-carbon fouling performance and smooth engine running.

Hot detonators are preferred in various industries, including automotive, marine, aerospace, and other industrial applications. They are recommended for reliable ignition and avoiding misfiring, as higher operating temperatures prevent carbon deposits on electrodes. Iridium ignitors also have a high melting point and consistent spark, improving fuel efficiency and reducing misfires. Their remarkable durability and wear resistance help them last up to 25% longer compared to platinum spark plugs.

Advanced ignitors with advanced material types, designs, and better operational results are expected to experience upward growth in the automotive sector due to the rising demand for high-performance vehicles requiring advanced ignitors for better combustion efficiency.

How Is Technological Advancement Complementing Spark Plug Sales?

Implementation of stringent environmental regulations and emission norms to reduce the carbon footprint and curb global warming led to the development of modern gasoline engines capable of giving high mileage and low emission without compromising performance.

These next engines are compact and require a special type of ignition system leading to innovation in spark plug technology. Market players are experimenting with various materials and making design modifications to meet the requirements.

The development of long and thin spark plugs that can be attached in a small headspace of the engine is estimated to drive the market demand for spark plug. The launching of iridium spark plugs which have higher life provides superior combustion, and can work in corrosive environment during marine application is estimated to further accelerate the market demand.

Modern engines work on elevated gas pressure where electric spark plugs are not that effective. The use of plasma-assisted spark plugs in such special conditions is presumed to enhance efficiency.

With demand for modern spark plug consistently rising, rapid development is estimated to boost the spark plug market growth.

The automotive industry is a rapidly growing end-use industry. Global expansion in the production of vehicles is propelling the demand for spark plugs,” - says Nikhil Kaitwade, Associate Vice President at Future Market Insights (FMI).

Why Is Automotive Spark Plug Gaining Popularity?

An automotive spark plug is expected to register exceptional growth owing to strict government emission norms and increasing demand for fuel-efficient vehicles. Rising private investments in the manufacturing sector and growing economy in developing nations are forecasted to boost automotive sales directly influencing automotive spark plug market growth.

Which Product Category May Experience Greater Demand?

Cold spark plugs are expected to grow substantially during the forecast period as the cold spark plugs firing end takes time to heat and provides a faster rate of heat transfer as compared to other types of spark plugs. Increasing demand for 4-stroke gasoline engines across the world is expected to drive the cold spark plugs demand even further.

Why is Iridium Type Spark Plug Gaining Traction?

An increase in demand for the iridium spark plug is anticipated especially from the marine sector as the iridium spark plug facilitates optimum power and combustion leading to improved engine performance. It also has longevity similar to platinum spark plugs and is thus used in newly launched automotive. Increasing production of automobiles is forecasted to drive the iridium spark plug market growth.

What Opportunities Are Prevalent in Sales Channel Segment?

Growing consumer preference towards vehicles with reliable ignition systems working in extreme conditions is causing OEMs to develop advanced spark plugs which are highly efficient and compact in size. High demand for modern spark plugs is forecasted to boost market sales in upcoming years.
