Choosing the Right Spark Plugs for Your 1958-1964 Nissan 1000
Keep your classic Nissan 1000 running smoothly with the correct new spark plugs.
- Choose standard copper spark plugs from Autolite or Champion; avoid expensive platinum or iridium plugs.
- Always check and set the spark plug gap before installation, likely between 0.031-0.035 inches.
- Plan to replace your spark plugs every 12,000 miles for optimal engine performance.
- Symptoms like rough idle, poor acceleration, and hard starting are strong indicators of worn spark plugs.
Is It Time for New Spark Plugs?
Even on a durable engine like the one in your Nissan 1000, spark plugs are a wear item. They won't last forever. If you're noticing any of these issues, your plugs might be worn out or dirty.
- Hard Starting: The engine turns over but takes a long time to fire up, or won't start at all.
- Rough Idle: You can feel the engine shaking or vibrating more than usual when the car is stopped.
- Poor Acceleration: The car feels sluggish or hesitant when you press the gas pedal.
- Engine Misfires: The engine may stumble, hesitate, or jerk while you're driving.
- Worse Gas Mileage: You find yourself filling up the tank more often than you used to.
Choosing the Right Aftermarket Spark Plug
For a vehicle like the 1958-1964 Nissan 1000, finding original "OEM" parts is no longer practical. Aftermarket parts are the standard for keeping these classics on the road. The good news is that the simple, standard copper spark plugs available today are very similar to what your car used when it was new.
Keep It Simple: Copper is Best
Modern engines use expensive spark plugs made with platinum or iridium to last for 100,000 miles. Your Nissan 1000's ignition system was not designed for these plugs. They offer no performance benefit and can sometimes run worse. A fresh set of standard copper plugs will perform better than old, worn-out premium plugs. Stick with basic, reliable copper plugs and change them more frequently.
Brand Quality: Autolite vs. Champion
Both Autolite and Champion are long-standing American brands that make suitable spark plugs for your vehicle. For an engine of this vintage, brand choice is less critical than making sure the plug is new, clean, and gapped correctly. Champion was an original equipment supplier for similar Datsun engines of the era, making them a historically appropriate choice. One specific compatible part is the Champion Copper Plus N12YC. Autolite also offers compatible plugs that are widely available and provide reliable service. Ultimately, either brand will serve your Nissan 1000 well.
How Much Do New Spark Plugs Cost?
Spark plugs are one of the most affordable maintenance parts you can buy. Replacing them is a cheap way to keep your engine healthy.
| Part Type | Price Range (Set of 4) |
|---|---|
| New Aftermarket (Autolite, Champion) | $14.00 - $57.20 |
| New OEM | Not Available |
Frequently Asked Questions
How often should I change the spark plugs on my Nissan 1000?
For this type of engine with a points ignition and using standard copper plugs, a good rule of thumb is to inspect and re-gap the plugs every 3,000-5,000 miles. It is recommended to replace them entirely every 12,000 miles to ensure top performance.
What is a spark plug gap and why is it important?
The gap is the tiny space between the two electrodes at the end of the spark plug. The spark has to jump this gap. If the gap is too small or too large, the spark will be weak, leading to poor engine performance. Always check the gap with a feeler gauge before installing new plugs. A common gap setting for similar Nissan/Datsun engines of this era is between 0.031 and 0.035 inches.
Can I replace the spark plugs myself?
Yes, absolutely. Replacing spark plugs on a 1958-1964 Nissan 1000 is a very simple job for a DIY mechanic. The plugs are easy to access on top of the engine. You only need a few basic tools, like a spark plug socket and a ratchet.
Are there any recalls or known issues for my car's spark plugs?
No. There are no active recalls or technical service bulletins (TSBs) from Nissan or the NHTSA regarding spark plugs for the 1958-1964 Nissan 1000. This is not surprising for a vehicle of this age.
