Many people mistakenly believe that there is no need to protect the wiring components inside the engine. This issue is completely wrong! Critical components like spark plugs always need the best protection to ensure efficient operation.
If you are wondering how to install spark plug wire heat shields, the following answers will be just what you need! Find out now!

Heat Layer
When the electrical power comes into connection with the plug, it generates heat and increases the resistance of the wires. This problem creates the risk of burning the spark plug cable in your engine.
The best suggestion for this would be to use a heat layer to reduce the resistance caused by heat. In addition, heat production is significantly controlled as this heated layer is manufactured from a non-conductive material.
In general, the nature of this protective shell will be a great kind of protection to help keep the conductors from melting.
Answer: How To Install Spark Plug Wire Heat Shields?
When it comes to heat layers, several variations need mentioning, such as lava boots, insul-boots, heat layer tapes, and HP boots. The installation process is quite similar, but each type has a few different details. Please refer to the following details:
Insul boots install
This type of insulation is quite common and is often used for making heat layers. This material is heat-reflective and can withstand temperatures up to 1200 degrees F.
Step [1]
The first step in buying insul-boots is to pay attention and ensure that it has eight layers. This note is generated because the spark plugs in the engine are mostly eight.
Next, you need to wait for the engine to cool completely to be safe and open the hood to determine the spark wires.
Step [2]
You should remove all wires of the cylinder peak for the most convenient installation.
Step [3]
In this step, you need to put the wire into the layers. It’s quick and simple, isn’t it! Especially on the top part of the layer, a ring helps keep them in place.
Step [4]
You need to pay attention and correctly place the loops at the boot’s top, middle, and bottom. You will easily return them to their original position if they separate.
Step [5]
After the covering process, you need to put the spark plug cable in the right position.
Lava boots install
This type of lava looks quite comparable to insul-boots, but this type has a twin wall. Specifically, this material is very tough and has good heat endurance (upward to 1200 degrees F) because it is designed with basalt material at high temperatures.
Step [1]
The first step you need to take is to separate the spark plug cables and check them for any cracks/tears.
Step [2]
Next, start fitting the spark plug cables into the lava boots
Step [3]
Be careful not to add or apply too much weight during the sliding of the boot. If you apply too much pressure, the big ends of the plug won’t come out of the boots.
Step [4]
This type of lava will not have a ring on the top similar to insul-boots, so you need to keep the bigger end.
Step [5]
In this step, you will start reassembling the plugs. In particular, at the end of the boots, you should put them on the upper part and see them as soon as you open the hood.
Step [6]
After the fitting process, you need to check it again to ensure it is ok. The headers part needs to be separated from the heat layers of the plug.
HP boots install
HP is a type of boots with a structure and installation markedly different from those mentioned above. Specifically, they are constructed with ceramic and stainless steel insulation.
Moreover, it has a rather stereotypical nature and appearance and will suit those who require flexible boots. Clearly, “HP” boots are designed with a straight, 90-degree, and 135-degree structure. These constructions have made it possible for HP to withstand temperatures up to 1800 degrees F.
Step [1]
The first step is always removing the plugs and checking for errors to fix them immediately.
Step [2]
With three types of HP structures, including straight, 90 degrees, and 135 degrees, you can choose the right type for the location you want to install.
Step [3]
The 135-degree type will be a great choice if your spark plugs are near the headers. If you choose this type, it will help keep the headers effectively spaced.
Step [4]
The engine is compact, and you will not be able to put boots on if you choose a straight heat layer, and it is certainly not the optimal choice.
Step [5]
The 90 degrees textured heat layer is the best recommendation because it’s designed to match the cylinders and headers. The great thing is that you won’t need the ring as it won’t come out of the spark plugs.
Step [6]
Since this HP is not as flexible as the others, it offers slight overheating.
In the last step, you can put the plugs in their original position and proceed to check if they are loose or not. Note that check carefully to avoid it coming loose from its initial position. Once done, you can shut the hood and complete the mounting process.
How Can I Use Them?
To install the heating layer, you need to use tape to stick on top of the layers. You need to create an outer layer that doesn’t leave any gaps. If you feel uncertain, you can apply another layer.
Final Thoughts
Surely the things related to how to install spark plug wire heat shields should now be easy after referring to the above information. Installing a heat shield is essential if you don’t want plug-in problems.
Installing the heating layer is also a good opportunity to help you check the plug and the lines. Hope the details above will help you complete the job well!
