Description
Ceramic spark plug boots are critical to maintaining reliable ignition performance under high heat and demanding conditions. Factory rubber boots degrade over time, leading to misfires and inconsistent combustion in high-rpm applications. This 8-pack ceramic boot kit provides superior heat resistance and dielectric strength to ensure consistent spark delivery across all eight cylinders.
Ceramic construction resists thermal cycling better than standard rubber, reducing the risk of boot cracking or separation from the spark plug terminal. The 90-degree angle configuration fits standard HEI and distributor-cap setups, making installation straightforward on most small-block and mid-size engines.
