Spark Plugs
Advanced Insulation and Electrode Design for Reliable Ignition
J.C.A.P. spark plugs feature high-density ceramic insulators, manufactured for consistent quality and performance. The thickened insulator nose delivers excellent dielectric strength and mechanical durability, ensuring reliable operation in modern high-performance engines. Precision-engineered electrodes provide outstanding electrical conductivity, heat resistance, and ablation resistance—maintaining stable ignition over extended use.
Durable Shell Construction for Strength and Heat Management
The plug shells are built with enhanced malleability, toughness, and hardness to reduce the risk of breakage. Their improved thermal conductivity supports efficient heat dissipation, enhancing overall durability and helping the spark plug perform reliably under high engine stress.

PRODUCT OVERVIEW

Spark plugs play a crucial role in engine combustion by delivering the high-voltage spark needed to ignite the air-fuel mixture. A well-designed spark plug must withstand extreme pressure, rapid temperature changes, and constant electrical load. J.C.A.P. spark plugs are engineered to deliver consistent ignition, smoother engine starts, and reliable long-term performance across a wide range of vehicle types and driving conditions.
