Choosing the Right Spark Plugs for Your 1982-1989 Chrysler New Yorker
Get your classic New Yorker running smoothly with the correct new aftermarket spark plugs for its specific engine.
- You must identify your engine (2.2L, 2.6L, or 3.0L) to buy the correct spark plugs.
- High-quality aftermarket brands like NGK and Denso are excellent choices, but some owners find these older Chryslers run best on standard Champion plugs.
- Always check and adjust the spark plug gap before installation, even if they are pre-gapped.
- No specific recalls or TSBs for spark plugs exist for this vehicle; failures are due to normal wear.
Symptoms of Failing Spark Plugs
When your New Yorker's spark plugs are worn out, they can't create a strong enough spark. This leads to incomplete combustion and several noticeable problems. You might experience a rough idle, where the car shakes or sputters when stopped. Other common signs include difficulty starting the engine, reduced power when accelerating, and worse gas mileage than usual. A check engine light may also appear, with codes indicating an engine misfire (e.g., P0300).
Choosing the Right Aftermarket Spark Plug
While Chrysler originally used Champion brand plugs in many vehicles from this era, today's aftermarket offers a wide range of quality options. The best choice depends on your budget and performance goals. It is critical to buy the correct plugs specified for your exact engine (2.2L, 2.6L, or 3.0L), as they are not interchangeable.
Spark Plug Brand Tiers
| Tier | Brands | Notes |
|---|---|---|
| Standard Replacement | Autolite, Champion | These are typically basic copper-core plugs, similar to what the car came with from the factory. Some owners report their New Yorker's ignition system is sensitive and runs best on standard Champion plugs. Autolite is also a reliable and affordable choice for a standard tune-up. |
| Premium Aftermarket | NGK, Denso, Bosch | NGK and Denso are highly regarded for their quality control and are often used as original equipment by many automakers. Their V-Power (NGK) or standard nickel plugs are excellent, reliable upgrades over basic copper plugs. Bosch is another quality option, though some mechanics prefer NGK or Denso for non-European vehicles. |
| Specialty / Performance | MSD, Crown Automotive | MSD offers plugs geared towards high-performance applications, which are generally not necessary for a stock engine. Crown Automotive specializes in Chrysler parts and can be a good source for OEM-style components. |
Check the Gap
Even if a spark plug is advertised as "pre-gapped," you should always verify the gap with a feeler gauge or gapping tool before installation. The correct gap specification is essential for a strong spark and can be found in your vehicle's service manual. An incorrect gap can cause misfires and poor performance.
Known Issues, Recalls, or TSBs
Searches of the National Highway Traffic Safety Administration (NHTSA) database and other technical resources did not reveal any specific recalls or Technical Service Bulletins (TSBs) related to spark plugs for the 1982-1989 Chrysler New Yorker. Any issues with spark plugs on a vehicle of this age are typically due to normal wear and tear.
Frequently Asked Questions (FAQ)
Which brand of spark plug is best for my New Yorker?
While Champion was a common original equipment brand, many owners and mechanics recommend NGK or Denso for their high quality and reliability. However, some older Chrysler ignition systems perform best with the basic Champion copper plugs they were designed for. If you're unsure, starting with NGK or Champion is a safe bet.
Should I use copper, platinum, or iridium plugs?
Your New Yorker's original plugs were standard copper plugs. Copper is an excellent conductor but wears out the fastest, typically needing replacement every 20,000-30,000 miles. Platinum and iridium plugs last much longer (60,000-100,000+ miles) but are more expensive. For a stock 1980s vehicle, standard copper or nickel alloy plugs (like NGK V-Power) provide excellent performance for the price.
Do I need a mechanic to change my spark plugs?
Changing spark plugs on this generation of New Yorker is a straightforward job that most DIYers can handle with basic tools. The key is to work on one cylinder at a time to avoid mixing up the spark plug wires, which must be reconnected in the correct order for the engine to run.
What happens if I don't change my spark plugs?
Ignoring worn spark plugs will lead to a gradual decline in engine performance. You'll likely experience rough running, poor fuel economy, and hesitation when you accelerate. In the long run, frequent engine misfires can potentially damage other components, like the catalytic converter.
