Keep spark energy where it belongs with the ThunderCore PRO ThunderSpark Coil Boot 900-P2035, an OE Replacement boot that restores the insulative path between the ignition coil and the spark plug in coil-on-plug (COP) and coil-near-plug (CNP) systems. It drops in across a broad range of Chrysler, Dodge, Jeep and RAM platforms — see the fitment list below.
- OE Replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry for consistent high-voltage insulation and secure coil-to-plug contact.
- Restores ignition insulation: replaces worn or cracked boots to help maintain proper spark isolation and reduce voltage loss.
- Heat & chemical resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
Over time coil boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. If a failed boot is the cause of those symptoms, installing this replacement restores the insulation and can help support smoother running. Diagnose the ignition system to confirm the boot is the culprit before replacing.
