Hybrid Engines and an Aging Gasoline Fleet Keep Spark Plug Revenue Growing at 2.15%
Global spending on automotive spark plugs reached USD 4.86 Billion in 2025 and should total USD 4.96 Billion in 2026 before climbing to USD 6.01 Billion by 2035, a 2.15% CAGR in Radial Insights' estimate.
The automotive spark plugs market in this report covers ignition plugs for gasoline, flex-fuel, gas and hydrogen spark-ignited engines in passenger cars, light commercial vehicles, two-wheelers and vehicle-derived small engines, sold to vehicle makers and through the replacement channel. Glow plugs for diesel engines, ignition coils, plug wires, pre-chamber igniters for large stationary engines and industrial cogeneration plugs are excluded.
Electrification removes spark plugs only from battery electric vehicles. Every hybrid and plug-in hybrid still carries a gasoline engine, and those engines often run hotter and leaner, which favors long-life iridium and ruthenium plugs. The International Energy Agency's Global EV Outlook 2026 shows electric and plug-in hybrid cars at about 25% of global new car sales in 2025, while EU data show full hybrids alone took 34.5% of 2025 registrations.
The fastest-growing segment is plug-in hybrids and range extenders at 7.40% CAGR, and the fastest-growing region is Asia Pacific (APAC) at 2.90% CAGR. Iridium is the fastest-growing major electrode material at 3.60%, as automakers specify 100,000 mile service intervals.
Supply is also being reshaped. Denso and Niterra signed a deal in September 2025 to move Denso's spark plug and exhaust sensor business to Niterra, then Denso moved in October 2026 to terminate it, saying demand for diverse powertrains has lasted longer than expected. In the United States, bankrupt First Brands Group began winding down Autolite operations in March 2026.

Iridium Leads Value and Ruthenium Is the Fastest-Growing Electrode Material
Iridium plugs are the largest value segment because nearly every new gasoline and hybrid engine from Toyota, Honda, Hyundai, Volkswagen and Ford ships with them, and they grow at 3.60%. Ruthenium and other precious metal designs grow fastest at 4.10% from a small base, used where engines run very lean or with high exhaust gas recirculation. Platinum grows at 1.60% as it is gradually displaced by iridium. Copper and nickel plugs grow at only 0.40% and survive mainly in older cars, two-wheelers and small engines; NGK still added 5 nickel references to its European range in 2025-2026 alongside 21 Laser Iridium parts.
Plug-in Hybrids and Range Extenders Are the Fastest-Growing Powertrain Segment
Gasoline ICE-only vehicles still use most plugs but grow at only 0.80%. Hybrid electric vehicles grow at 6.10%, because hybrids took 34.5% of EU registrations in 2025 and lead in Japan as well. Plug-in hybrids and range extenders grow fastest at 7.40%, led by Chinese brands such as BYD, Li Auto and Leapmotor. Gas and hydrogen engines grow at 5.20%, as CNG cars in India and hydrogen truck engines in Europe need specialized high-voltage plugs.
Two-Wheelers Outgrow Cars in Vehicle-Type Demand
Passenger cars are the largest vehicle group at 2.10% CAGR, followed by light commercial vehicles at 1.90%. Two-wheelers grow fastest at 3.40% because motorcycle and scooter fleets in India, Indonesia, Vietnam and Africa are large, mostly gasoline and need frequent plug changes. Small engines and marine grow at 1.40% as battery tools take share in lawn equipment.
Aftermarket Growth Is More Than Three Times OEM Growth
The OEM channel grows at 0.90% because each new car needs plugs only once at assembly and battery models take some of the build mix. The aftermarket grows at 2.90%, since the global gasoline fleet keeps aging and many vehicles go through two or three plug sets during their life.

Market Dynamics
Market Trends
Japanese Suppliers Reverse Course on Consolidation
Denso and Niterra signed a business transfer agreement on September 1, 2025 to move Denso's spark plug and exhaust gas sensor business, including oxygen and air-fuel ratio sensors, to Niterra. In October 2026, Denso said it would terminate the agreement after reviewing its CORE 2030 plan, because demand for diverse powertrains has lasted longer than expected across regions. The U-turn signals that suppliers now see combustion parts as a cash-generating business for at least another decade.
Aftermarket Catalogs Expand for Hybrid and Downsized Engines
Niterra's NGK Ignition Parts released 26 new aftermarket spark plugs for combustion and hybrid cars in five batches between September 2025 and March 2026, including 21 Laser Iridium references. The company expects them to cover a car parc of nearly 9 million vehicles in 2026, with 20% vehicle-in-operation growth over two years. Three references alone fit almost three million Hyundai and Kia vehicles.
US Aftermarket Brands Change Hands
First Brands Group, owner of Autolite, entered bankruptcy in 2025. In March 2026 it began winding down Autolite operations and agreed to sell 12 brands, including Autolite, Fram and Trico, to PGI Northstar for USD 25 million, subject to court approval. Retailers and distributors are rebalancing shelf space toward NGK, Denso, Bosch and Champion.
Plug-in Hybrids Keep Spark-Ignited Engines in Volume Production
China produced 34.53 million vehicles in 2025 and 16.63 million new energy vehicles, according to OICA, and a large share of those NEVs are plug-in hybrids and range extenders. These engines run for long periods at steady load, which suppliers address with finer iridium tips and stronger insulators.
Restraints and Challenges
Battery Electric Vehicles Remove Plugs Entirely
Battery electric cars need no spark plugs. Electric and plug-in hybrid cars made up about 25% of global new car sales in 2025, and more than half of new cars in China, according to the IEA's Global EV Outlook 2026. As battery models gain share, OEM plug demand per vehicle built falls; we estimate this trims around 1.2 percentage points from the CAGR over the decade.
Longer Service Intervals Reduce Replacement Frequency
Iridium plugs often last 100,000 miles or more, compared with roughly 30,000 miles for older copper plugs. Higher value per plug offsets part of the loss, but each vehicle buys fewer sets during its life, which slows aftermarket volume even as revenue per unit rises.
Flat Production in Western Markets
OICA data show European vehicle production fell 0.8% to 17.2 million units in 2025 and Americas output fell 2.1%, per the OICA 2025 production summary. With weak OEM volumes in two large regions, plug makers rely on the aftermarket and on Asian programs for growth.
Precious Metal Prices and Counterfeits Squeeze Margins
Iridium, platinum and ruthenium prices are volatile, and plug makers can pass costs to automakers only with a lag. In the aftermarket, counterfeit plugs sold through online marketplaces in Asia, the Middle East and Africa undercut branded products and can damage engines, eroding brand trust.
Growth Drivers
Hybrid Sales Add Gasoline Engines Faster Than Battery Cars Remove Them
Hybrid electric cars took 34.5% of EU new car registrations in 2025, the largest share of any powertrain, and hybrid sales rose 13.5% during the year. Toyota, Honda, Hyundai, Kia, Renault and Ford all expanded hybrid line-ups, and each of these vehicles carries four plugs or more at assembly plus replacements over its life. Hybrid engines also run Atkinson cycles and high compression, which call for iridium or ruthenium tips rather than nickel. We estimate that hybrid growth contributes about +1.0 point of annual growth to the automotive spark plugs market through 2035.
China's Plug-in Hybrid and Range-Extender Boom
China built 34.53 million vehicles in 2025, a record, and new energy vehicle output reached 16.63 million units, up 29%. Plug-in hybrids and extended-range models from BYD, Li Auto, Leapmotor, Changan, Geely and Chery make up a large part of that NEV total, and every one of them uses a gasoline engine. Chinese automakers also exported more than 7 million vehicles in 2025, many of them plug-in hybrids, spreading plug demand to export markets. Weichai Torch Technology and other domestic suppliers compete here with Niterra, Denso and Bosch. This driver accounts for roughly +0.8 points of the forecast CAGR.
An Aging Gasoline Fleet Supports Replacement Demand
The world sold 99.8 million new vehicles in 2025, according to OICA, and most of the vehicles on the road remain gasoline powered. In the United States, where electric and plug-in hybrid cars were only about 10% of 2025 new car sales according to the IEA, the gasoline fleet keeps getting older, and older engines need plug changes at regular intervals. Niterra expects its new European aftermarket references to cover a 20% rise in vehicles in operation over two years. We credit fleet aging with about +0.6% of yearly growth, mainly through the aftermarket channel, which grows at 2.90%.
Opportunities
Hydrogen and Gas Engine Ignition
Hydrogen combustion engines for trucks and CNG engines for cars and three-wheelers need plugs that resist pre-ignition and higher voltage. Gas and hydrogen engines grow at 5.20% in our model. Suppliers with ceramic and electrode know-how, such as Niterra, Denso and Bosch, can supply these programs at premium prices.
Two-Wheeler Replacement Markets in Asia and Africa
Two-wheelers are the fastest-growing vehicle segment at 3.40%. Hundreds of millions of motorcycles and scooters in South and Southeast Asia and Africa use gasoline engines and change plugs often. Brands that build distribution in these markets and fight counterfeits can capture steady volume.
Asia Pacific Holds 44.30% of Spark Plug Revenue and Grows Fastest at 2.90%
Asia Pacific (APAC)
Asia Pacific (APAC) accounted for 44.30% of the automotive spark plugs market in 2025, worth USD 2.15 Billion. APAC revenue rises to USD 2.87 Billion by 2035, a 2.90% CAGR and the fastest of any region. China produced 34.53 million vehicles in 2025, Japan 8.41 million and India 6.49 million, according to OICA. Japan is also home to Niterra and Denso, the two largest plug makers.
North America
North America held 24.60% of 2025 revenue, about USD 1.20 Billion. North American sales reach USD 1.39 Billion by 2035 at a 1.50% CAGR. The United States produced 10.24 million vehicles and sold 16.7 million in 2025, and electric and plug-in hybrid cars were only about 10% of US new car sales. The March 2026 wind-down of Autolite operations by First Brands Group is reshaping the US replacement brand mix.
Europe
Europe represented 21.10% of the 2025 total, or USD 1.03 Billion. European revenue grows to USD 1.15 Billion by 2035 at 1.15% a year, the slowest rate. European vehicle production fell 0.8% to 17.2 million units in 2025, and hybrids took 34.5% of EU registrations while petrol-only cars took 26.6%. NGK's 26 new European references cover nearly 9 million vehicles.
Latin America
Latin America took 5.40% of 2025 revenue, worth USD 0.26 Billion. Latin American revenue climbs to USD 0.34 Billion by 2035 at 2.50% a year. Brazil's flex-fuel fleet runs on high ethanol blends, which raise electrode wear and shorten plug life, and Mexico's assembly plants supply plugs for US-bound engines.
Middle East
The Middle East held 2.80% of the 2025 market, about USD 0.14 Billion. Middle East revenue reaches USD 0.18 Billion by 2035 at a 2.60% CAGR. Gulf vehicle markets remain dominated by gasoline SUVs and pickups, and battery electric cars hold a low single-digit share of sales, which protects both OEM and replacement demand.
Africa
Africa accounted for 1.80% of 2025 revenue, about USD 0.09 Billion. African revenue rises to USD 0.12 Billion by 2035, growing at 2.80% a year. Vehicle sales in Africa jumped 22% to 1.29 million units in 2025, per OICA, and large motorcycle taxi fleets in Nigeria, Kenya and Uganda create frequent plug replacement.
