How do you protect spark plug wires from heat?

How To Protect Spark Plug Wires From Headers And Melting

1. #1. Tape the Wires.
2. #2. Heat Shields.
3. #3. Insul-Boots.
4. #4. HP Boots.
5. #5. Lava Boot Shield.

Why are my spark plug wires melting?

From what you’ve described, the cylinder head overheated which caused the wires to melt. Your engine is overheating and the white smoke from the exhaust indicates that the head gasket is blown or cracked.

Does heat affect spark plug wires?

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.

How much heat can a spark plug wire handle?

The optimal firing end temperature is approximately 500°C (932°F) to 800°C (1472°F). The two most common causes of spark plug problems are carbon fouling (< 450°C) and overheating (> 800°C).

What makes a spark plug hot or cold?

A spark plug is said to be “hot” if it is a better heat insulator, keeping more heat in the tip of the spark plug. A spark plug is said to be “cold” if it can conduct more heat out of the spark plug tip and lower the tip’s temperature.

Is it bad if spark plug wires touch?

As long as the spark plugs and wires are good not a problem for the wires to touch. They don’t fire at the same time and the distance between wires is always more than the spark plug gap.

What happens if you don’t protect spark plugs from heat?

Without it, the boots will walk up the wire over time, exposing the spark plug to the heat you’re trying to protect them from. Insul-Boots™ spark plug wire protector can withstand temperatures of 1,200-degree Fahrenheit constant and 2,000-degree intermittent, and they are available in a variety of colors.

How hot should a spark plug wire get?

A typical street engine with headers will normally maintain underhood temperatures between 300 and 500 degrees at the header tube closest to the spark plugs. Under a heavy load or increased work, this temperature can double — our Lava Boot spark plug wire heat shields can still manage the heat.

Why does my spark plug jump when it gets hot?

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.

Do I need spark plug wire protectors for my engine?

However, for higher horsepower engines or supercharged/turbocharged applications, the normal exhaust temp can be much higher, making HP Boots™ spark plug wire protectors the better choice. We also know that you don’t normally need protection on every spark plug boot.
