The HKS Super Fire M-Series Spark Plug for Nissan RB20DE(T) offers exceptional ignition performance and reliability for high-performance and turbocharged engines. Engineered with a 0.6mm Iridium alloy center electrode and a platinum chip on the outer electrode, this spark plug ensures long-lasting durability and resistance to carbon buildup. Its short-type outer electrode and anti-vibration design provide stability under high-load conditions, while the thermal edge and spark support gap optimize combustion efficiency. The high melting point of iridium, combined with a nickel-plated housing, allows the plug to withstand extreme pressures and minor knocking without deterioration, ensuring consistent engine performance.
The M-Series plugs are specifically designed to handle colder heat ranges, with this particular NGK Range 8 plug ideal for heavily modified or high-boost turbo setups. Heat range is crucial in turbo engines because it controls how efficiently heat is transferred from the plug tip to the cylinder head, directly impacting reliability and performance. Using a colder plug in extreme conditions helps prevent pre-ignition and detonation, maintaining safe and consistent performance even under the highest combustion temperatures. HKS M-Series Spark Plugs are sold individually, making it easy to select the perfect plug for your engine’s needs while ensuring smooth starts, responsive acceleration, and durability under demanding driving conditions.
