Spark Plug Replacement Guide for the 1983-1986 Dodge Power Ram 50
Keep your classic Power Ram 50 running strong with the right set of new spark plugs.
- For the Mitsubishi engine in your Power Ram 50, NGK and Denso are the most recommended aftermarket brands.
- Always verify the spark plug gap with a tool before installation; do not rely on the 'pre-gapped' claim on the box.
- Symptoms like rough idle and hard starting are common signs of failing plugs, but can also point to issues with plug wires, the distributor cap, or rotor.
- Standard copper plugs are a great, cost-effective choice that matches the vehicle's original ignition system design.
Signs of Failing Spark Plugs
When your spark plugs are wearing out, your truck will give you several warning signs. Because these plugs are a simple maintenance item, it's best to replace them before symptoms become severe.
Common Failure Symptoms
- Rough Idle: The engine may shake or vibrate more than usual when stopped at a light.
- Trouble Starting: The engine may crank for a long time before it finally starts, or it might not start at all.
- Engine Misfires: You might feel a hesitation or stumble from the engine during acceleration.
- Reduced Fuel Economy: If you notice you're filling up the gas tank more often, weak spark could be the cause.
- Poor Acceleration: The truck may feel sluggish or down on power when you press the gas pedal.
Choosing the Right Aftermarket Spark Plugs
For a vehicle from this era, original equipment (OEM) spark plugs are generally unavailable. The good news is that today's aftermarket brands offer excellent, and often superior, options. Your truck has a Mitsubishi engine, which typically performs best with Japanese brands like NGK or Denso.
Brand Quality Tiers
- Top Tier (Recommended): NGK and Denso are widely considered the best choices for Japanese engines. They offer standard copper plugs that work great, as well as modern iridium and platinum plugs for longer life. Many owners find these brands provide the most reliable performance.
- Standard Tier: Brands like Bosch, Champion, and Autolite offer quality spark plugs that meet or exceed original specifications. Champion was a common OEM supplier for many American brands, and their standard copper plugs are a reliable and budget-friendly choice for the Power Ram 50.
- A Note on Plug Material: Your truck's original ignition system was designed for standard copper spark plugs. While more expensive platinum or iridium plugs will work and last longer, they won't necessarily provide a performance boost. Sticking with a quality copper plug from a brand like NGK or Denso is a great, cost-effective strategy.
Known Issues, Recalls, or TSBs
There are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA related to spark plugs for the 1983-1986 Dodge Power Ram 50. Any issues you experience are likely due to normal wear and tear, not a manufacturing defect.

Frequently Asked Questions
How often should I change the spark plugs on my Power Ram 50?
For standard copper spark plugs, a good interval is every 20,000 to 30,000 miles. If you install longer-life platinum or iridium plugs, you can extend that interval significantly, often to 60,000 miles or more.
Should I use anti-seize on the new spark plugs?
Yes, it's a good idea. Applying a small amount of anti-seize compound to the threads of the new plugs will make them much easier to remove next time. Be careful not to get any on the electrode tip. Also, be aware that using anti-seize can affect torque readings, so tighten them gently to avoid over-tightening.
I changed my spark plugs but the engine still runs rough. What else could it be?
If new, correctly gapped plugs don't solve the problem, check other parts of the ignition system. On the Power Ram 50, this includes the spark plug wires, distributor cap, and rotor. Old vacuum lines can also cause leaks that lead to a rough idle.
Do I need special tools to change my spark plugs?
You will need a ratchet, a few extensions, and a specific spark plug socket (usually 5/8"). A spark plug socket has a rubber insert that holds the plug, making it easier to pull out and install without damage. You will also need a spark plug gap tool to check the gap.
