Spark Plug Connectors

It's the critical link between your ignition system and the spark plug. The spark plug connector (or boot) has two vital jobs: transferring high-voltage electricity and sealing the spark plug well from moisture, oil, and dirt. A brittle, cracked, or oil-soaked boot can cause the spark to arc to the engine block, leading to a dead cylinder and a check engine light.

Often, these connectors are damaged during removal or simply wear out from heat exposure. Replacing them is a low-cost, high-impact step to prevent frustrating misfires and protect your new spark plugs.
