- Brands like NGK and Denso are excellent OEM-quality choices for this Mitsubishi-based vehicle.
- Symptoms like rough idle, hesitation, and poor MPG are strong indicators that your spark plug wires need replacement.
- Replacing spark plug wires is a simple, beginner-friendly DIY job that requires no special tools.
Is Your Colt Running Rough? It Could Be the Spark Plug Wires
If your Dodge Colt is experiencing issues like a rough idle, hesitation when you accelerate, or a general lack of power, old spark plug wires could be the cause. Over time, the insulation on these wires breaks down from engine heat and vibration. This allows the electrical energy to leak out before it reaches the spark plug, resulting in a weak or non-existent spark. This is often called an engine "misfire."
Choosing the Right Aftermarket Wires for Your Colt
Since the 1984-1995 Dodge Colt is a rebadged Mitsubishi, parts made for the Mitsubishi Mirage, Lancer, or Eagle Summit of the same era often fit. When shopping for new wires, it's important to match them to your specific engine, as different options like the 1.5L, 1.6L, and 1.6L Turbo were available. For this vehicle, aftermarket brands offer excellent quality, often meeting or exceeding the original factory specifications.
Aftermarket Brand Quality Tiers
| Tier | Brands | Description |
|---|---|---|
| OEM Quality / Daily Driver | NGK, Denso | Both NGK and Denso are well-regarded Japanese brands, often supplying original parts for Mitsubishi. They are known for excellent fit, durability, and reliable performance, making them a top choice for a standard replacement. |
| Performance Upgrade | MSD, Granatelli | These brands focus on high-performance applications. They often feature thicker 8mm wires with lower resistance for a stronger spark, which can benefit tuned or turbocharged engines like the 1.6L 4G61T. |
| Standard Replacement | Standard Wires (SMP), Walker Products, Prenco | These brands provide reliable, budget-friendly options that meet factory requirements. They are a good choice for owners looking for a functional and affordable repair. |
Known Issues for This Vehicle
No recalls or Technical Service Bulletins (TSBs) specifically for spark plug wires on the 1984-1995 Dodge Colt were found during research. The primary issues are related to normal wear and tear. Due to the age of these vehicles, the original wires are almost certainly degraded and should be inspected or replaced. Symptoms like a rough idle, misfiring, and hard starts are very common indicators of failing wires on the Colt and similar Mitsubishi models.
Frequently Asked Questions (FAQ)
How often should I replace my Colt's spark plug wires?
For a vehicle of this age, a good rule of thumb is to inspect them every 30,000 miles and replace them every 60,000 to 100,000 miles, or whenever you replace the spark plugs. However, if you see any visible damage like cracks, burns, or melting, they should be replaced immediately.
Can I use wires from a Mitsubishi Mirage on my Dodge Colt?
Yes, in most cases. The 1984-1995 Dodge Colt shares its platform and engines with the Mitsubishi Mirage and Lancer, as well as the Eagle Summit and Plymouth Colt. Always confirm the part fits your specific year and engine size before purchasing.
What's the difference between 7mm and 8mm wires?
The measurement refers to the diameter of the wire's outer jacket. Performance brands like MSD often use a thicker 8mm or 8.8mm wire, which provides better insulation and can handle higher voltage from performance ignition systems. For a stock Colt, a standard 7mm wire from a quality brand like NGK or Denso is perfectly adequate.
Do I need special tools to change spark plug wires?
No special tools are required. A set of spark plug wire pullers can be helpful to avoid damaging the boots, but often you can remove them by hand by twisting and pulling firmly on the boot itself—never pull on the wire. It's a good idea to apply a small amount of dielectric grease to the inside of the new boots to protect against moisture and make future removal easier.
Technical Specifications
The key is to match the wire set to your specific engine. The 1984-1995 Dodge Colt used several Mitsubishi engines, including the 4G15 (1.5L) and 4G61/4G61T (1.6L). Always verify fitment for your year and engine code.
