Attention car enthusiasts and DIY mechanics! This NYTKL spark plug boot terminal kit is exactly what you need for ignition system repairs or upgrades. The kit includes 8 silicone boots and 8 terminals - plenty for most vehicles and some extras just in case. The 90-degree angled design is super practical for tight engine bays where straight boots just won't fit properly. Made from high-grade heat-resistant silicone, these boots can handle extreme engine temperatures without cracking or hardening over time. The snug fit creates a solid barrier against dust, debris, oil splashes, and moisture that can cause voltage leaks or misfires. Each boot measures about 1.77x1.38 inches with a 0.71-inch diameter, designed to fit wire diameters from 6mm to 10mm (about 0.24 to 0.39 inches). Installation is straightforward - just slide the silicone boot over your ignition wire and secure it onto the terminal. No special tools or advanced mechanical skills required! The vibration-resistant design keeps connections stable even during engine movement, ensuring consistent performance. These work with cars, trucks, motorcycles, boats, and most other vehicles with standard or high-performance ignition systems. The compact size makes storage easy, and having a full set means you can do complete tune-ups or keep spares for future repairs. If you're dealing with rough idling, misfires, or just want to upgrade old, cracked boots, this affordable kit provides professional-quality components that will keep your ignition system running smoothly for miles to come.
