Coil-on-plug ignition systems—found in virtually every modern vehicle—are vital to optimal engine performance, much like the heart is to the human body. In this system, each cylinder is equipped with an individual ignition coil mounted directly above the spark plug, connected via a critical component: the coil-on-plug boot.

At PPE & PJC, we specialize in the manufacturing of high-performance coil-on-plug boots, including silicone ignition coil boots, spark plug boots, and spark plug wire boots. Our products are engineered to deliver exceptional durability and protection, shielding the ignition coil and center electrode from dust, moisture, and mechanical stress. Whether you’re in need of OEM replacement or high-heat performance, our coil boots are designed for superior fit, electrical insulation, and long-term reliability.
