IWISS iCrimp Spark Plug Wire Crimper - Ratchet Stripper for 7.0–8.5mm Wires, Ergonomic PP+TPR Handles

This compact hand tool combines a wire stripper and crimper into a single ratcheting device engineered for DIYers, professional shops, and racers who build or repair ignition cables. Finished in polished metal with a black oxide coating and fitted with dual‑compound PP+TPR handles, the iCrimp prioritizes corrosion resistance, ergonomic comfort, and consistent crimps for silicone‑jacketed spark plug wires and terminals.

How does the iCrimp crimper ensure consistent crimps every time?

The iCrimp uses a ratcheting mechanism that only releases after full compression, eliminating under‑crimped terminals and variability between operations. Precision‑machined jaws align terminals and wire cores so each crimp meets the same mechanical standard.

• Ratcheting release guarantees full compression before opening.
• Polished jaw surfaces for secure terminal hold and alignment.
• Black oxide finish reduces corrosion on contact surfaces.

Can this tool handle different spark plug wire sizes and terminal types?

Yes — the iCrimp is sized for ignition wires in the 7.0–8.5 mm diameter range and works with a variety of common spark plug terminals. It’s intended for silicone‑insulated wires and the terminals used in aftermarket and performance ignition cable assemblies.

• Capacity tailored for 7.0–8.5 mm spark plug wires.
• Compatible with many standard ignition terminals and end fittings.
• Useful for both repair and new cable assembly tasks.

What features boost comfort and reduce hand fatigue during repetitive jobs?

The handle pair combines PP and TPR materials to provide a non‑slip grip and lessen vibration transfer, while the ratchet reduces required squeeze force for repetitive crimps. The tool’s balance and finishing also help minimize hand strain during longer sessions of cable work.

• Two‑component PP+TPR ergonomic handles for slip resistance.
• Ratcheting action lowers user effort per crimp.
• Optimized jaw polish and finish for smooth operation.

What maintenance and care will keep the crimper working well?

Wipe the tool clean after use, apply light oil to the pivot occasionally, and store in a dry place to protect the black oxide finish. Avoid using the crimper on non‑rated materials or wire sizes outside its intended range to preserve jaw geometry.

• Keep jaws clean and lightly lubricated at the pivot point.
• Store in a dry toolbox or pouch to avoid rusting.
• Do not force oversized wires or incompatible terminals through the jaws.

Who is this for: The IWISS iCrimp is built for performance-minded mechanics, racers, and backyard tuners who assemble or repair their own ignition leads. It suits professional shops needing a repeatable crimping solution, club racers building custom lengths, and DIYers upgrading or replacing spark plug wires where consistent electrical and mechanical connections are important.
