NGK Spark Plug and Cap Combo for 2025+ 85cc Carb Models with TSP Head

This specialty spark plug and cap combo is designed specifically for 2025+ KTM 85SX, Husqvarna TC85, and GasGas MC85 models fitted with a TSP CNC Head and Insert. It is not compatible with OEM heads or stock plug caps.

The NGK spark plug is required by the TSP head design and must be paired with the included NGK short-style plug cap. Using the stock plug cap with this plug will result in a poor fit and potential ignition issues.

Engineered to perform in demanding 85cc two-stroke conditions, the NGK plug features:

• A fine-wire iridium center electrode and platinum ground electrode for consistent, high-energy spark
• Superior anti-fouling performance and throttle response
• Triple-sealed construction, copper core, and ceramic insulation for enhanced durability and heat management
• Designed to withstand the high RPM and temperature demands of competitive youth and amateur racing

When running a TSP 85cc head, this plug and cap combo is required for correct fitment and optimal performance. Whether you’re tuning for racing or reliability, this is the spark solution that keeps up with your build.
