In coil-on-plug (COP) and coil-near-plug (CNP) setups, the coil boot forms the insulative path between the ignition coil and the spark plug. Over time these boots can degrade from heat, vibration, or chemical exposure — signs the boots may need replacing include arc-through, misfires, or hard starting. If worn boots are the cause, this kit replaces them.
- OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Heat & Chemical Resistant: high-temp silicone and reinforced materials help resist oil, fuel, and under-hood heat.
- Restores Ignition Insulation: replaces worn or cracked boots to support proper spark isolation and limit voltage loss.
- Complete Kit Coverage: includes the boots, springs, and insulators needed for full-cylinder service — ideal for tune-ups and repairs.
