The titanium spark plug lead protection sleeve is mainly made of volcanic rock material which is heat-resistant, chemically resistant and anti-fouling. This significantly enhances the durability and strength of the product, while also being soft and elastic. High-horsepower engines generate high temperatures, and the hardening and cracking of the ignition lead can lead to engine misfire and malfunction of the ignition system. The titanium spark plug lead protection sleeve provides excellent protection for this. The working temperature reaches 800℃, and the instantaneous temperature can reach 1200℃. The standard inner diameter is 20mm, and other specifications can be customized.
