8 PCS Spark Plug Protect Boots, 1200 Degree Spark Plug Wire Boots Heat Shield Protector Sleeve, 6 Inch Heat Shield Thermal Protection Insulator

**** The Yonput 8 PCS Spark Plug Protect Boots are designed as heat shield protectors for spark plug wires, promising to withstand up to 1200 degrees. Customers generally report a mixed experience when it comes to usability and effectiveness. Many appreciate the appropriate length of the boots, especially for those with high-heat applications like ceramic headers. Users noted that the product looks sturdy and functions well in certain applications, such as on a 2003 Silverado, where it appears to effectively prevent spark issues. However, the installation process seems to be a significant hurdle, with several customers expressing frustration over how difficult it is to fit the boots over the plugs. Additionally, some users reported a messy installation experience, mentioning that it leaves a heavy black residue on hands. Competibility issues have also been highlighted, specifically regarding claims of fitting certain engine models, such as Tundras, where users found that these shields do not fit well within ignition coils. Some feedback was more critical, with claims that the protectors could cause connection issues, potentially causing wires to jump off or burning plug lead wires due to excessive heat. In summary, while the Yonput spark plug boots have the potential to protect against high temperatures effectively, their installation challenges, compatibility problems, and potential to cause connection issues may deter some users from recommending the product. **
