The ceramic boots will withstand up to 2,000 degrees F. If you are running headers with close tolerances, have an engine bay with little room or an RV with boots that melt because of heat, these wire kits are the answer for burnt and melting boots.

Heat damage – Engine heat can burn wire insulation and boots. A damaged boot can impede proper spark plug wire seating and performance. Wire insulation that's damaged by head can allow voltage to jump to the ground rather than jumping the gap at the bottom of the spark plug.

The most obvious sign of faulty spark plug wires is your vehicle just feels a little 'off. ' It would probably start slowly with reduced gas mileage but could progress to no acceleration. Faulty spark plug wires or spark plug misfires can also cause problems starting your engine, a rough idle, and loss of power.

Could be as simple as you are trapping compressed air when you slide the rubber boot over the plug, especially with silicone rubber type. I squeeze the boot to let air escape after I hear the metal clip click on the plug end. You might also slide a screwdriver up between boot and plug. Otherwise, the clip may be loose.

Ceramic insulator Most spark plugs used today feature a single-ceramic insulator made from aluminium oxide, with other types of ceramic materials like porcelain used in the past. This provides many benefits, including thermal conductivity and superior insulation.

Ceramic insulators for spark plugs are important components responsible for the dielectric barrier to generate high-voltage pulses required to ignite the air–fuel mixture and for providing mechanical support to the center electrode.

If you notice any sparks or burning smells coming from outlets or appliances, it's important to shut off the power immediately and call an electrician. Bad wiring can be extremely dangerous and should always be addressed by a professional.

If your spark plugs are fouled or damaged, it can lead to a host of problems including reduced gas mileage, slow acceleration, engine misfires and trouble starting the engine.

Failing spark plug wires can cause:

• Engine misfiring,
• Increased fuel consumption,
• Lack of power,
• Stalling,
• Rough idle,
• Fuel system problems, such as fuel in the cylinder,
• Problems starting your car,
• An engine warning light to illuminate,

Worn/failed spark plugs, coil packs, or spark plug wires can trigger your check engine light to come on. In today's cars, if a spark plug fails and can no longer ignite the air-fuel mixture, then the most obvious event should be the check engine light coming on or even flashing.

The spark from the coil changes direction; instead of traveling through the boot, from the coil to the spark plug, it will shoot out the side of the bad boot and spark to the cylinder head. This causes that cylinder to misfire.

If still intact detach the spark plug wire and boot from the spark. Plug. You can place a drop of liquid dish soap into the boot to assist in pulling it off the wire and terminal.
