A Guide to Choosing a Spark Plug Wire Set for Your 1983-1993 Dodge Ram 50
Get your classic truck running smoothly by understanding which spark plug wires are right for its Mitsubishi-made engine.
- The 1983-1993 Ram 50 is a Mitsubishi truck; choose parts from brands known for Japanese vehicle quality.
- NGK and Denso are the most recommended brands for a perfect fit and long-term reliability.
- Performance wires from brands like MSD or Taylor are not necessary for a stock engine and provide no extra power.
- This is a very easy DIY job. Replace the wires one at a time to avoid mixing up the firing order.
Signs of Failing Spark Plug Wires
Spark plug wires don't last forever. The constant heat and vibration in the engine bay cause them to wear out. When they start to fail, you'll notice your truck isn't running right. Common symptoms include:
- Rough Idle: The engine shakes or runs unevenly when you're stopped.
- Engine Misfires: You may feel the truck hesitate or stumble when you accelerate. This is a very common sign.
- Trouble Starting: A weak spark makes it harder for the engine to fire up, especially in the cold.
- Poor Acceleration: The truck feels sluggish and doesn't have the power it used to.
- Worse Gas Mileage: An engine that isn't firing correctly wastes fuel.
- Audible Ticking: You might hear a rhythmic clicking sound from the engine area, which is the sound of electricity arcing from a cracked wire to a metal part of the engine.
Choosing the Right Aftermarket Wires for Your Ram 50
Original factory (OEM) Mopar wires for this truck are no longer available. Fortunately, the aftermarket offers excellent options. Since your truck has a Japanese engine, choosing a brand known for quality in Japanese vehicles is the best strategy. Here’s how the available brands stack up.
Tier 1: OEM-Quality Aftermarket
These brands are trusted by mechanics and are the best choice for reliability and correct fit on your Ram 50's Mitsubishi engine.
- NGK: NGK is a top-tier Japanese brand famous for ignition parts. Their wire sets are known for excellent quality, perfect fit, and long-lasting performance. Many Japanese vehicles used them as the original part. You cannot go wrong with NGK.
- Denso: Denso is another major OEM supplier for Japanese automakers. Their wire sets are considered identical to factory parts in fit and quality. They use high-quality silicone and strong connectors, making them a safe and reliable choice.
Tier 2: Performance & Heavy-Duty
These brands are designed for high-performance or racing engines. They often feature thicker wires and are more expensive. For a stock Ram 50 engine, they are generally not necessary but are a high-quality option.
- MSD: Known for their red performance wires, MSD offers very low resistance for a strong spark. However, owner reviews are mixed; some experience long life, while others report early failures on daily drivers. They are often considered overkill for a stock engine.
- Taylor Cable: Taylor is another well-regarded performance brand, known for durability and use in race cars. They offer excellent heat resistance and are a solid, high-quality choice if you want something more heavy-duty than stock.
Tier 3: Standard Aftermarket Replacements
These brands offer a good balance of quality and price for a daily-driven truck.
- Standard Motor Products (SMP): SMP is a long-standing aftermarket company that makes a huge range of parts. Their wires are generally seen as a reliable and good-quality replacement for the original parts.
- Walker Products: Walker is another established brand that offers standard replacement parts that meet factory specifications.
Tier 4: Economy Brands
Brands like Prenco and Crown Automotive fall into this category. While they are the most affordable, their long-term durability and fit may not match the higher-tiered brands. For a part this critical to engine operation, it is usually worth spending a little more for a brand like NGK or Denso.
Pro Tip: Easy Installation
This is a great DIY job. To avoid mixing up the firing order, replace the wires one at a time. Pull the wire off cylinder one, find the matching length wire in the new set, apply a small amount of dielectric grease to the inside of the new boots, and click it into place on the distributor and spark plug. Repeat for the remaining cylinders.

Frequently Asked Questions (FAQ)
Should I replace the spark plugs at the same time?
Yes, it is highly recommended. If your wires are old, your spark plugs probably are too. Replacing the wires, spark plugs, distributor cap, and rotor all at once is a complete ignition tune-up that will ensure your engine runs its best.
Do I really need to use dielectric grease?
Yes. A small dab inside each boot helps seal out moisture and makes it easier to remove the wires in the future. It also helps ensure a good electrical connection.
Can I just replace the one bad wire?
It's best to replace the entire set. All the wires have been exposed to the same heat and wear. If one has failed, the others are likely weak and will fail soon.
Are thicker 8mm performance wires better than standard 7mm wires for my truck?
For a stock engine, no. A quality 7mm wire set from a brand like NGK or Denso will provide more than enough spark. Thicker performance wires won't add any power to a stock Ram 50 and are not necessary.
Technical Specifications
Wire sets are specific to your engine (2.0L, 2.4L, 2.6L, or 3.0L V6). Ensure you buy the correct set for your vehicle. Most standard replacement sets will be 7mm diameter with a carbon or magnetic core and silicone jackets.
