Masuma has significantly expanded its range of spark plugs. In addition to the well-known iridium and platinum spark plugs, as well as Double-series plugs featuring precious metals on both electrodes, Masuma has introduced new Copper Core spark plugs with nickel-plated electrodes—a simple and affordable solution.

The Masuma lineup now includes spark plugs for vehicles from 30 automotive brands, including:
AUDI, BMW, CHANGAN, CHERY, CHEVROLET, CITROËN, DAIHATSU, FORD, HONDA, HYUNDAI, INFINITI, KIA, LAND ROVER, LEXUS, MAZDA, MERCEDES-BENZ, MITSUBISHI, NISSAN, OPEL, PEUGEOT, RENAULT, SCION, ŠKODA, SUBARU, SUZUKI, TOYOTA, VOLKSWAGEN, VOLVO.

Masuma Copper Core Spark Plugs

Standard spark plugs with a copper core and nickel-plated center electrode.

✔ Service life: up to 30,000 km.
✔ Affordable plugs without precious metals.
✔ Ensure reliable engine operation.
✔ Suitable for a wide range of vehicles and equipment.

Masuma Copper Core spark plugs can replace more expensive iridium and platinum spark plugs, provided the ignition system allows it. Replacement interval: 30,000 km.

Masuma Platinum & Masuma Iridium Spark Plugs

Featuring a fine-wire central electrode made of precious metal.

✔ Service life: up to 80,000 km.
✔ Improves combustion efficiency in cylinders.
✔ Self-cleans effectively, reducing carbon buildup.
✔ Reduces ignition coil load, extending component lifespan.
✔ Offers more stable and longer-lasting performance than standard plugs.

2 years ago we discussed the “precious” spark plugs with platinum and iridium, as well as their distinctions from cheap nickel spark plugs. People who still use conventional plugs replacing them every 50k km, who don’t want to “overpay”, are strongly advised to read the article. It will make clear why your ignition coils burn out.

Since then the Masuma series has been extended. The following existing plugins:
 ● Iridium
 ● Platinum
 ● Iridium+Platinum
were complemented with Double Platinum and Double Iridium . Let’s discuss their key features.

Let us recall the advantages of platinum and iridium plugs :
– Stable spark-plug gap and extended lifetime of those spark plugs due to low erosive wearing of the central electrode.
– Better combustion of the fuel-air mixture due to a thin electrode and a more powerful spark.
– Reducing the load on the ignition coils and their breakdown risk.

What’s special about Double?

The Double series spark plugs don’t have precious metal only on the center electrode, but on the side electrode as well, and this prevents it from burnout and extends the spark plug lifetime. This series is kind of Super Long Life spark plugs.

Masuma DOUBLE PLATINUM are spark plugs with a platinum tip of the central electrode and a platinum solder on the side electrode. Reliable operation up to 100,000 km, keeping the spark-plug gap stable.

Masuma DOUBLE IRIDIUM are spark plugs with the technology of a needle grounding counter electrode made of iridium. Two ultra-thin iridium electrode tips increase the density of the electric discharge, improving the combustion efficiency of the cylinder mixture as possible and giving the engine the full power. The lifetime of Masuma DOUBLE IRIDIUM spark plugs is 120,000 km.

Masuma Iridium + Platinum & Double Platinum Spark Plugs

Fine-wire center electrode made of precious metal with a platinum tip (pad) welded on the ground electrode.

✔ Service life: up to 100,000 km.
✔ Enhances combustion, improving engine performance.
✔ Self-cleans efficiently, minimizing deposits.
✔ Reduces stress on ignition coils, increasing durability.
✔ Maintains a stable spark gap over time.
✔ Extended lifespan compared to conventional spark plugs.

Masuma Double Iridium Spark Plugs

Ultra-fine iridium center electrode with a needle-shaped ground electrode made of iridium.

✔ Service life: up to 120,000 km.
✔ Optimizes fuel combustion, boosting engine power and efficiency.
✔ Provides superior self-cleaning, preventing carbon buildup.
✔ Reduces ignition coil load, ensuring longevity.
✔ Maintains a stable spark gap, ensuring consistent performance.
✔ Maximizes durability, offering the longest lifespan among Masuma spark plugs.
