Splitfire Power
Ignites Every Drive

Built for consistent ignition and high-temperature performance on every road, these spark plugs deliver dependable starts, reduce misfires over time, and maintain strong combustion even under demanding driving conditions.

Engineered For Power And Consistency

Each component is crafted to support cleaner combustion, reduce performance loss over time, and ensure reliable function under varying engine loads and temperatures.

Stronger Combustion

Dual-electrode design supports powerful ignition, improves fuel efficiency, and maintains stable performance even during extended drives or high-speed acceleration.

Heat-Resistant Build

Durable construction helps prevent fouling, resists corrosion, and maintains structural integrity in high-temperature environments over time.

Reliable Engine Response

Consistent firing promotes smooth starts, reduces the chance of misfires, and supports steady throttle response under varying driving conditions.

Driven By Performance Since Day One

The story started in the early 1990s when a team of engineers set out to address common issues faced by drivers—weak ignition, poor fuel economy, and frequent replacements. Drawing from motorsport testing and road performance data, they focused on creating components that could support stronger combustion and greater durability under pressure.

Over the years, the brand gained attention among performance enthusiasts and everyday drivers alike. Its consistent results and simple yet effective engineering led to widespread use across various vehicle types. Today, the brand remains focused on developing solutions that support cleaner operation, stronger starts, and dependable function across all driving conditions.
