  • Another indication of a blocked spark plug boot is engine hesitation.
  • You should inspect your car if the engine power is reduced.
  • Another common sign is engine surging.

Below, you’ll now discover how to free the jammed spark plug boot. The technique is outlined below.

  • To begin, you must first choose which blocked spark plug boot you wish to remove. You must be able to reach the spark plug wire’s termination point.

  • It’s possible that the affected cable will be damaged or could be dangerous. Normally, the spark plug wire boot should be held in your hand. Then twist in each direction and pull together. Your wire will not break or be damaged if you do this. It guarantees the safety of your cable.

  • Pulling the wire in a circle allows the connection to separate from the top of the spark plug, making it more accessible and reducing the strain on the wire. After that, you must pull straight so that it may discharge from the connection because otherwise, you risk breaking or damaging the stuck spark plug boot. Finally, to replace a spark plug boot, simply slide it into place and grip it until it is fully seated.

Is it Dangerous for Cats to Have a Stuck Spark Plug Boot?

There is always this confusion in knowing if it is dangerous for cars to have a stuck spark plug boot. The answer is unfortunately affirmative. A car cannot be driven with a stuck spark plug boot.

Because the spark plug boot is used to start the vehicle and does not come into contact with the electrical spark, if the spark plugs boot breaks or becomes stuck in the wire, the automobile may be damaged.

Until you replace it, your car will not start. Your car engine, on the other hand, can enter into the electrical spark and explode. As a result, we may conclude that releasing the trapped spark plug boot is critical.

SPARK PLUG BOOT Installation Instructions

First, inspect the spark plug leads to check if it’s safe to replace the boot and cap. It won’t hurt if the plug wire is covered with heat shrink and has worn through to the metal braid; simply brush it off and tape it.

Wrap the braid with some form of braid and tape it tightly if it has worn through but not into the plug, lead core. Solder wick works well to cover the damaged area on the braid and can be soldered in place if desired.

Step 1. Remove the old spark plug boot and all of the old heat shrink, but leave the heat shrink covering the braid and wire in place.

Cleanly cut the wire’s end off. When you install the new boot and cap, you’ll probably shorten the plug lead by 12 to 34 inches. 1&1/4 inch of heat shrink is removed, leaving the braid and inner plug lead exposed.

Step 2. Wrap the plug wire with 12-inch 12 heat shrink, then 14-inch 3/8 heat shrink, 34-inch 3/8 heat shrink, and finally the wire crimp ring.

Step 3. Hook the longer end of the spark plug terminal spring into the location you want the top of the plug wire to be, then cut the inner plug wire off so the spring will just go past the end of the plug wire with some resistance.

Use a heat gun or lighter to shrink a 12-inch length of 3/8 heat shrink over the end of the spark plug wire. Before shrinking the short length of heat shrink, I applied a small bit of medium CA on the spring wires.

Step 4. To implant the silicone plug boot, lubricate it with liquid soap or silicone lubricant and insert the spring. The spring terminal’s longer wire connects to the top of the plug boot.

Make that the terminal is in the boot in a straight position. Make sure your spark plug is in the boot and that the top button is in the spring. Take a little screwdriver and square up the spring if it isn’t straight. Take care not to rip or puncture the boot.

Step 5. On the steel shell, bend the tabs past 90 degrees. Use a set of pliers with a flat nose. Make sure not to bend the flange on the shell. Hook the other shell under the front tab and two top tabs, then lay the boot in the cover with the tabs.

Squeeze the shells’ bottoms together and hook the bottom tab. Cover the wire with the braid by sliding it up over it. Cover the shells by sliding the crimp ring up over the braid. With a sharp pair of cutters, cut off any excess braid. Install the snap ring gap at a 45-degree angle to the cover seams.

Don’t bend the ring; it needs to be snug to keep the cap on the spark plug and provide good ground. Squeeze the shells together with a clamp, then crimp the tabs down with a good pair of square-nosed pliers.


To conclude, it is to mention that the procedure for removing a jammed spark plug boot is outlined below. I hope you have a thorough understanding of everything. You have two more ever-rising concerns regarding your vehicle’s security. You could suffer for a long time if you don’t.
