Ultra-Low Resistance Kevlar® Core
At the center of every ignition wire is an Ultra-Low Resistance Kevlar® reinforced conductor.
Advantages include:
- Efficient spark transfer
- Increased tensile strength
- Excellent durability
- Consistent ignition performance
Kevlar reinforcement helps the wires resist stretching and vibration while maintaining dependable conductivity.
Spiral-Wound Conductor Design
The wires utilize a spiral-wound conductor, a common design in performance ignition systems.
Benefits include:
- Reliable voltage delivery
- Reduced electromagnetic interference (EMI)
- Stable ignition timing
- Improved engine performance
This design provides an excellent balance of spark energy and electronic noise suppression.
High-Temperature Silicone Boots & Sleeves
Premium silicone boots and protective sleeves help the ignition wires withstand demanding engine bay conditions.
Features include:
- High heat resistance

- No crimping required
- Factory-style fitment
Installation can typically be completed with basic hand tools.
Why Replace Spark Plug Wires?
Spark plug wires naturally deteriorate over years of:
- Engine heat
- Oil exposure
- Electrical stress
- Vibration
Common symptoms include:
- Rough idle
- Engine hesitation
- Random misfires
- Hard starting
- Reduced fuel economy
- Check Engine Light
Replacing worn ignition wires restores proper spark delivery and improves overall engine efficiency.
Ideal for LS-Based GM Trucks
This ignition wire set is well suited for:
- Daily drivers
- Tow vehicles
- Work trucks
- Street performance builds

- High-mileage maintenance
Fresh ignition wires help keep GM V8 engines running smoothly under all driving conditions.
Installation Tips
For best results:
- Replace one ignition wire at a time.
- Match each wire to the factory routing.
- Fully seat every ignition boot.
- Keep wires away from exhaust manifolds whenever possible.
- Inspect spark plugs during installation and replace them if necessary.
Proper routing maximizes ignition performance and wire longevity.
Warranty Coverage
