What is a coil-near-plug ignition system?

A coil-near-plug (CNP) system places the ignition coil directly on top of the spark plug, or very close to it. This eliminates the need for traditional spark plug wires that run from a distributor or coil pack to each plug, reducing potential resistance and improving spark energy.

What does the blue jacket on these connectors do?

The blue jacket is made of high-temperature silicone. This material is chosen for its ability to withstand the heat found in a typical engine bay, helping to protect the internal wiring and maintain the integrity of the electrical connection.

Do these connectors come with new spark plugs?

This product is a kit of ignition wire connectors only. It does not include spark plugs. You will need to purchase spark plugs separately if your job requires them.
