Construction & Design

The NGK Direct Ignition Coil Boot is expertly crafted from high-grade silicone, chosen for its excellent thermal stability and resistance to cracking or degradation under extreme engine conditions. This material ensures the boot maintains flexibility and a secure seal over time, even in harsh environments.

Internally, the boot features precision-engineered springs that guarantee firm electrical contact with the spark plug terminal, minimizing voltage loss. The integrated ferrite resistors serve a dual purpose: they suppress electrical noise that can interfere with onboard electronics and prevent flashover, which can cause misfires and reduce engine performance.
