Choosing the Right Spark Plug Wire Set for a 1955-1966 Studebaker Commander
Keep your classic Studebaker's V8 running strong by understanding how to select the correct new aftermarket spark plug wire set.
- Failing spark plug wires are a common cause of rough running, misfires, and poor fuel economy in a Studebaker Commander.
- Modern aftermarket wires from brands like Standard, Walker, or FAST are generally superior in quality and durability to the original 1960s technology.
- Replacement is a simple DIY task; the key is to swap wires one at a time to maintain the correct engine firing order.
- Ensure the wire set you purchase is listed as compatible with your specific year and V8 engine to guarantee proper wire lengths and fit.
Is Your Studebaker Telling You It Needs New Wires?
The spark plug wires on your 1955-1966 Commander live in a harsh environment. Decades of engine heat, vibration, and exposure to fluids can cause them to break down. When they fail, the spark can weaken or become inconsistent, leading to noticeable problems. It's a common maintenance item that can make a big difference in how your classic drives.
Common Symptoms of Failing Spark Plug Wires
- Rough Idle: The engine may shake or vibrate more than usual when stopped.
- Engine Misfires: You might feel a stutter or hesitation from the engine, especially when accelerating.
- Hesitation or Power Loss: The car may feel sluggish and not accelerate as quickly as it should.
- Poor Fuel Economy: Inefficient spark means wasted fuel, leading to more frequent trips to the gas station.
- Difficulty Starting: A weak spark can make it harder for the engine to fire up.
- Visible Damage: Check the wires for cracks, burns, or brittle insulation. Sometimes you can even see an electrical arc in the dark if there's a bad wire.
Choosing the Right Aftermarket Wire Set
For a vehicle as old as the 1955-1966 Commander, original equipment (OEM) wires are no longer available. The market consists of New Old Stock (NOS) parts, which are rare and expensive, and modern aftermarket replacements. Fortunately, today's aftermarket wires often use materials and construction that are superior to the originals, offering better heat resistance and electrical conductivity.
Brand Tiers for Your Commander
When shopping for a new set, you'll find several options. The key is to choose a set that is specifically listed for your vehicle's year and V8 engine to ensure correct lengths and boot angles.
- Good - Standard Replacement (Standard Wires, Walker Products): Brands like Standard Motor Products and Walker Products offer direct-fit, OE-style replacement wires. These are an excellent choice for a stock or daily-driven Commander. They are designed to meet original specifications for fit and performance, providing reliable spark delivery and noise suppression for your radio. Reviews suggest Standard Motor Products wires are durable and fit well. Walker Products also emphasizes meeting or exceeding OEM specifications with features like high-temperature silicone boots.
- Better - Performance Wires (FAST): Brands like FAST (Fuel Air Spark Technology) offer performance-oriented wires. These often feature lower electrical resistance, which means more spark energy reaches the plug. FAST FireWire sets, for example, have very low resistance (around 25 ohms/ft) and use materials like Kevlar and double-layer silicone for enhanced heat and abrasion resistance. This can be a good upgrade if you have a modified ignition system or simply want the most robust option available.
A Note on Appearance
Some owners prioritize a period-correct look. While many modern wires are black or gray silicone, some companies offer wires with vintage-style fabric braiding over modern, high-performance conductors. This gives you the best of both worlds: classic looks with modern reliability.

Frequently Asked Questions
Is replacing spark plug wires a DIY job?
Yes, this is a very straightforward job for a home mechanic. The most important rule is to replace the wires one at a time to avoid mixing up the firing order. Simply remove one old wire from the distributor cap and the corresponding spark plug, then install the new wire of the same length in its place.
Do I need special tools?
No special tools are required. A spark plug wire puller can be helpful to avoid damaging the boots, but often you can remove them by twisting and pulling carefully by the boot itself, not the wire. Applying a small amount of dielectric grease inside the new boots will make installation easier and help seal out moisture.
What's the difference between 7mm and 8mm wires?
The measurement refers to the diameter of the wire's outer jacket. Most original wires from this era were 7mm. Many modern and performance wires are 8mm or larger, offering thicker insulation for better heat protection and voltage retention. For a stock Studebaker, a quality 7mm or 8mm set will work perfectly fine.
Are there any recalls for my Commander's ignition wires?
No. There are no active recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) regarding spark plug wires for the 1955-1966 Studebaker Commander. This is expected for a vehicle of this age.
