Key Features
Heavy-Duty 10mm Wire Construction
The Michigan Motorsports wire set features 10mm ignition cables, offering increased insulation compared to factory wires.
Benefits include:
- Better heat resistance
- Reduced voltage leakage
- Increased durability
- Longer service life
The thicker jacket is particularly beneficial for performance trucks operating under high engine bay temperatures.
Ultra-Low 30 Ohms-Per-Foot Resistance
One of the standout features is the 30-ohm-per-foot spiral-core conductor.
Advantages include:
- Exceptional spark energy
- Minimal voltage loss
- Fast ignition response
- Reliable high-RPM performance
With significantly lower resistance than many OEM-style wires, these cables are well suited for modified LS engines.
Excellent EMI & RFI Suppression
The spiral-core design provides outstanding suppression of:
- Electromagnetic interference (EMI)
- Radio frequency interference (RFI)
This helps protect:
- Engine control modules
- Fuel injection systems
- Sensors
- Aftermarket electronics
Strong suppression is especially important for modern LS-powered vehicles with sensitive engine management systems.
High-Temperature Silicone & Fiberglass Sleeving
Each wire features a protective sleeve made from a silicone and fiberglass blend.
Benefits include:
- Excellent heat resistance
- Abrasion protection
- Increased durability
- Improved longevity near headers
The additional sleeve helps protect ignition wires from radiant exhaust heat and engine bay wear.
45-Degree Boots
Unlike many factory wire sets, Michigan Motorsports uses 45-degree boots at both ends.
Advantages include:
- Improved header clearance
- Cleaner wire routing
- Reduced boot stress
- Easier installation
These angled boots are especially useful on trucks equipped with aftermarket long-tube headers.
Made in the USA
The ignition wires are hand-built in the United States, providing additional confidence in manufacturing quality and consistency.
Available Color Options
Michigan Motorsports offers these ignition wires in multiple colors, including:
- Red
- Black
- Blue
- Gray
- Green
- Orange
- Purple
- Pink
- White
This allows enthusiasts to match their ignition wires to the overall engine bay theme.
Why Upgrade Spark Plug Wires?
Replacing aging ignition wires can help restore:
- Smooth idle
- Reliable starting
- Strong throttle response
- Consistent spark delivery
- Improved combustion efficiency
- Better engine performance
Fresh ignition wires are one of the simplest maintenance upgrades for higher-mileage LS engines.
Installation Tips
For the best results:
- Measure your existing wire length before ordering.
- Replace one wire at a time.
- Route wires away from exhaust headers.
- Fully seat each ignition boot.
- Use wire separators to prevent crossfire.
Proper routing maximizes ignition performance and wire longevity.

Frequently Asked Questions
Will these fit every LS truck?
They fit most GM LS trucks using 10-inch truck-style ignition wires. Measure your existing wires before ordering, as some later trucks use shorter car-style coil brackets.
Why are 30 ohms-per-foot ignition wires beneficial?
Lower resistance allows more ignition energy to reach the spark plugs while maintaining excellent EMI suppression for modern engine electronics.
Are these good for aftermarket headers?
Yes. The fiberglass heat sleeve and 45-degree boots are specifically designed to improve durability and clearance around headers.
Are these made in the USA?
Yes. Michigan Motorsports hand-builds these ignition wires in the United States.
