Heatshield Products Introduces Line Of Spark Plug Boot Protectors

New from Heatshield Products – their line of spark plug boot protectors. These protectors help to prevent performance loss and ignition system failure due to heat-damaged spark plug boots. See more details below.

Official Release:

When your engine isn’t firing on all cylinders like it’s supposed to, it can do more than just ruin your day. But the Heatshield Products line of spark plug boot protectors makes sure you’re not losing any performance or risking ignition system failure due to heat-damaged spark plug boots.

As ignition wires and spark plug boots become heat soaked, the electrical resistance of the wires increases. As resistance increases, the ignition system has to use more energy to push the spark to the spark plugs, meaning less energy for the spark. Engine misfires are possible, which can cause engine damage. And if there is enough resistance, there is a possibility of damage to the ignition system. Heatshield Products has developed a variety of spark plug boot protectors to help prevent heat-generated ignition issues.

Insul-Boot – Introduced more than 20 years ago, Insul-Boot features a rugged, double-wall high construction that reflects and dissipates heat. It is rated to withstand a constant 1,200 degrees F of constant heat, and 2,000 degrees F of intermittent heat. Insul-Boot has a 1-inch inside diameter, allowing it to fit almost every design and angle of spark plug boot, and it is available in a variety of colors.

Lava Boot Shields –Lava Boot Shields are made from proprietary volcanic-rock–based thermal-barrier material. Along with having a unique high-tech racing look, this material will stay flexible even after countless heat cycles. It also protects the spark plug boots from oil and common automotive chemicals. Rated for up to 1,200 degrees F of constant heat, and 2,000 degrees F of intermittent heat, Lava Boot Shields will fit just about any application and angle of spark plug boot from damaging heat.

HP Boots – For the ultimate spark plug boot protection from heat and underhood exposure, HP Boots feature heavy-duty 304 stainless steel construction and high-temp thermal-barrier material. Made for extreme-duty and -heat situations, they are rated for up to 1,800 degrees F of constant heat and 2,200 degrees F of intermittent heat.

Heatshield Products has engineered and manufactured heat-barrier products for more than 30 years, serving the performance and racing industry with the highest quality products at competitive prices. The company is family owned and operated, and is proud to make its products in the USA.
