Set of 8 high-performance HKS spark plugs for your tuned M60 and M62 engines. These plugs have a colder heat range, one step down from the factory specification, making them a superior choice for enthusiasts seeking to maximize performance. Ideal for setups with aggressively advanced ignition timing from a performance ecu tune/chip or forced induction systems such as superchargers, these plugs enhance combustion stability under high-performance conditions.

Advancing ignition timing by 10° can raise spark plug tip temperatures by approximately 70–100°C, which can push standard plugs beyond their optimal operating range. The colder heat range of these HKS plugs helps to dissipate heat more effectively, reducing the risk of pre-ignition and detonation. By maintaining a lower firing-end temperature, these plugs ensure consistent performance and reliability in engines operating at higher cylinder pressures and temperatures. This translates to smoother acceleration, improved power delivery, and enhanced durability for modified M60 and M62 engines pushing the limits of performance

 

 

Ultimate spark plug "M".


Ignitionability, durability, anti-insulation are all reinforced. HKS has made the best plug for both tuning engines and stock engines.


Features

- 0.6mm Iridium Alloy Center Electrode
The iridium alloy center electrode minimizes voltage requirements, enhancing ignition performance and extending durability, even under demanding conditions.

- Outer Electrode with Platinum Chip
Equipped with a square platinum chip, the outer electrode improves durability and, when paired with the iridium center electrode, boosts ignition performance. Its tapered and shortened tip design ensures proper ignition spacing while optimizing efficiency.

- Short-Type Outer Electrode (Anti-Vibration)
Designed with a shortened, lightweight structure, the outer electrode resists vibration, increasing its lifespan and reliability under harsh conditions.

- Thermal Edge
The ceramic insulator features a thermal edge that helps discharge carbon buildup caused by extended idling or varying combustion conditions, reducing misfires and ensuring consistent performance.

- Spark Support Gap
The spark support gap, located between the insulator tip and the base of the outer electrode, facilitates discharge to further prevent carbon deposits and maintain optimal ignition performance.

Performance and Efficiency

- Enhanced Ignition Performance
The advanced design reduces voltage requirements, ensuring reliable ignition even in challenging scenarios like lean air-fuel mixtures or high boost pressures.

- Superior Durability
Constructed with innovative materials and engineered for resilience, these plugs excel under extreme conditions such as continuous high load, circuit driving, or aggressive engine tuning.

- Reduced Carbon Deposits
The thermal edge and spark support gap work together to minimize carbon buildup, providing consistent ignition and improved engine efficiency across various operating conditions.
