A Guide to Aftermarket Spark Plugs for the 1984-1988 Dodge Mini Ram
Keep your classic Dodge van running smoothly with the right set of new spark plugs.
- For the 1984-1988 Dodge Mini Ram, standard copper-core spark plugs from brands like Champion, NGK, or Autolite are the best choice for value and performance.
- Always verify the spark plug gap before installation; do not assume they are correct out of the box. The specification is typically between 0.035" and 0.044".
- Replacing spark plugs is an easy, low-cost maintenance item that you can do yourself in under an hour.
- Symptoms like rough idle, poor gas mileage, and difficulty starting are strong indicators that your spark plugs need to be replaced.
Signs of Failing Spark Plugs
When your Mini Ram's spark plugs are worn out, the engine will let you know. The simple, non-computer-controlled engines in these vans make symptoms of bad plugs fairly obvious. You may notice one or more of the following issues:
- Rough Idling: The engine may shake or sound uneven when the van is stopped.
- Engine Misfires: You might feel a hesitation or stumble from the engine, especially when accelerating.
- Poor Fuel Economy: Worn plugs burn fuel less efficiently, meaning you'll be visiting the gas station more often.
- Hard Starting: A weak spark makes it difficult for the engine to fire up, especially in cold weather.
- Lack of Power: The van may feel sluggish and slow to accelerate because the cylinders aren't firing effectively.
No Recalls Found
A search of the National Highway Traffic Safety Administration (NHTSA) database found no recalls or technical service bulletins (TSBs) specifically related to spark plugs for the 1984-1988 Dodge Mini Ram.
Choosing the Right Aftermarket Spark Plugs
For a vehicle like the Dodge Mini Ram, aftermarket spark plugs are an excellent and affordable choice. The original plugs were basic copper-core types, and sticking with this technology is a reliable and cost-effective strategy. While more expensive platinum and iridium plugs are available, they often don't provide a noticeable benefit in older, carbureted engines and can sometimes be more prone to fouling.
Brand Tiers for Your Mini Ram
- OEM-Style/Recommended (Copper): Champion was a common original equipment supplier for Chrysler products of this era, making them a solid, reliable choice. NGK and Autolite are also highly-regarded brands that produce excellent standard copper plugs that work very well in these engines. These plugs are inexpensive and perform exactly as the engine was designed.
- Mid-Grade (Platinum): Brands like Bosch, Denso, and NGK offer platinum plugs. These can offer a longer service life than copper plugs, but it's important to ensure they are compatible with your older ignition system. For the Mitsubishi 2.6L engine, Japanese brands like NGK and Denso are particularly good choices.
- High-Performance (Iridium): While available from brands like NGK and Bosch, iridium plugs are generally considered overkill for the Mini Ram's stock engine. They won't harm anything, but you won't see a performance return on the higher cost compared to standard copper plugs.
Pro Tip: Always check the spark plug gap before installation! Even if plugs come "pre-gapped," they can be knocked out of spec during shipping. The correct gap for most Mini Ram engines is between 0.035" and 0.044", but check your vehicle's specific requirements.

Frequently Asked Questions
How often should I change the spark plugs on my Mini Ram?
For standard copper spark plugs, a good interval is every 20,000 to 30,000 miles. Since the job is easy and the parts are inexpensive, regular changes are a great way to keep your engine running at its best.
What is the correct spark plug gap?
The spark plug gap can vary slightly by year and engine. For the 2.6L engine, a gap of around 0.040"-0.044" is common. For the 2.2L, it's often around 0.035". Always verify the correct specification for your specific vehicle, as it is crucial for proper engine performance.
Can I use platinum or iridium plugs in my old van?
Yes, you can, and they will work. However, the simple ignition systems on these older, carbureted engines were designed for standard copper plugs. You are unlikely to see any performance gain from the more expensive plug types, so copper plugs offer the best combination of performance and value.
Is it hard to replace the spark plugs myself?
No, this is a very easy job for a DIY mechanic. The spark plugs on both the 2.2L and 2.6L four-cylinder engines are right on top and easy to access. With a basic socket set and a spark plug socket, the job can be done in under an hour.
