Ratchet Spark Plug Wire Crimping Tool Kit - 24PCS Terminals & Boots

In this review the Ratchet Spark Plug Wire Crimping Tool Kit is judged as a practical, do-it-yourself ignition wiring solution for homeowners and car enthusiasts handling spark plug coil connections. The kit's single biggest selling point is its purpose-built jaws sized for spark plug wire diameters of 8-8.5mm, which deliver firm crimps without damaging the wire. The reviewer found the ratcheting action and dual crimp/strip functions save time on repetitive work, and the included brass terminals plus rubber boots make the kit ready for restoring or replacing plug wire ends.

Key Features

• 8-8.5mm wire compatibility: The crimper is matched to spark plug wire diameters of 8-8.5mm so crimps are secure and consistent for these common ignition wires.
• Firm, damage-free jaws: The tool jaws ensure a strong grip and produce an efficient crimp without crushing or cutting the conductor.
• Anti-slip handles: PVC+TPR construction and an anti-slip handle reduce hand fatigue and make repetitive crimping more comfortable.
• Dual-function design: Built-in stripping and cutting features let users strip, cut and crimp with one tool, speeding up repairs.
• Complete terminal kit: Includes 24 brass terminals in 180, 90 and straight styles plus 24 black rubber boots to protect connections from dust and moisture.
• Multi-use application: Suitable for home electrical repairs and car circuit connections where spark plug coil terminals are required.

Who It's For

The kit is best for DIY mechanics, hobbyists and householders who work on ignition wires and need a compact, all-in-one tool for stripping and crimping plug wire ends. It fits tasks like replacing worn spark plug wire terminals, rebuilding coil leads, or preparing wires for custom routing where the 8-8.5mm diameter is used.

Professionals who require a wider range of terminal sizes or heavy daily use may want a more industrial-grade crimper and a broader terminal selection. Also, if your wiring uses thinner or thicker conductors than 8-8.5mm, look for a tool sized for that specific diameter.

Pros & Cons

Pros

• Kit matched to common spark plug wire diameter gives reliable crimps for ignition work.
• Ratcheting mechanism and dual crimp/strip function speed up repetitive jobs.
• Anti-slip PVC+TPR handles increase comfort during extended use.
• Includes a useful selection of brass terminals and protective black rubber boots.

Cons

• Limited to wires around 8-8.5mm diameter, so it is not a universal crimper for all automotive wiring sizes.
• The kit contents are basic; professionals needing many terminal styles or larger quantities may require additional parts.

Specifications
