Pro-Boot Spark Plug Wire Shield

September 2021 Products Web Exclusive

The new Heatshield Products patent-pending Pro-Boot Shield spark plug boot protector keeps spark plug boots from being damaged by underhood heat, including from exhaust manifolds or headers, thereby preventing ignition misfires or failure and potential engine damage.

Spark plug boots are constantly exposed to radiated or direct-contact heat, whether a vehicle has a cast-iron exhaust manifold or steel-alloy tubular exhaust headers. Unfortunately, the factory metal plug boot shields provide inadequate protection and often increase heat exposure because they get heat-soaked and then transfer that heat directly to the boots. If the silicone construction degrades, eventual failure is likely.

Pro-Boot Shield is rated for a constant 1,200 degrees F of radiant heat and 2,000 degrees F intermittent heat, which is possible through the use of Heatshield Products specially formulated Lava thermal-barrier material and additional heat insulation from the inner Tac Armor Liner.

Pro-Boot Shield’s sealable ends further block out heat by making sure heat cannot get trapped inside the boot’s airspace, while keeping dirt and debris from building up inside the boot. Pro-Boot Shield comes in pairs or sets of eight and is available in a Stealth Black finish or Lava carbon-fiber–style finish.

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 proudly makes its products in the USA.
