Spark plugs become a key factor in clean and complete combustion in any petrol engine. Clean and complete combustion is PARAMOUNT in performance tuning as the power produced is directly related to the force of the combustion. HKS offers spark plugs that are state of the art in terms of ignition technology. The Outer Electrode incorporates a square platinum chip which improves durability and when combined with the iridium center electrode boosts ignition performance. The Outer Electrode features a shortened tip design and tapered shape while maintaining the necessary space for proper ignition. New material and design improves durability, which allows for use under harder combustion conditions such as continuous high load during circuit driving or aggressive tuning. Improper combustion condi.
