Iridium is the top tier of spark plug technology, and this ENA set provides 8 high-performance iridium plugs designed for maximum durability and ignitability. Iridium plugs last the longest—often 100,000 miles or more—due to the extremely hard and fine metal electrode, which allows for a minimal spark gap and maximum efficiency.

Comparison Insights: Choosing Your Technology

When selecting the best spark plugs for your Lincoln Town Car, you’re primarily deciding between plug composition and service kit convenience.

For the common 4.6L V8, you have several excellent options. The NGK V-Power (Copper) is ideal if you are on a tight budget or enjoy performing maintenance frequently, prioritizing raw spark quality over longevity. If you want a significant boost in durability without jumping to the most expensive material, the NGK G-Power (Platinum) offers a great mid-range balance, lasting roughly 50,000 to 60,000 miles.

If maximum durability is your goal, the ENA Iridium Set provides the longest service intervals, making it the top choice for low-maintenance, high-mileage drivers.

For maintenance simplification, the ENA Platinum Spark Plug and Ignition Coil Pack Set provides the greatest immediate value, covering both plugs and coils. This is especially important for Town Cars experiencing intermittent misfires or rough idling, as often the coils are the root cause rather than just the plugs.

Finally, owners of older Town Cars (pre-1991) should ensure they select the 8 pc NGK V-Power Spark Plugs compatible with Lincoln Town Car 5.0L V8 specifically designed for the classic 5.0L engine configuration.

Complete FAQ about the Best Spark Plugs for Lincoln Town Cars

How do I know if my Lincoln Town Car needs new spark plugs?

Common symptoms include rough idling, decreased fuel economy, engine hesitation or stumbling during acceleration, and difficulties starting the vehicle. If your 4.6L V8 is over 60,000 miles since the last plug change, it’s likely time for new plugs.

What is the correct spark plug gap for a Lincoln Town Car 4.6L V8?

The correct gap setting for most 4.6L V8 engines (especially post-1998) is generally 0.054 inches. However, you should always consult your vehicle’s manual or the specification guide provided by the plug manufacturer to ensure the exact fitment and gap for your specific year model.

Can I install iridium spark plugs in a Town Car originally designed for platinum?

Yes, you can upgrade to iridium plugs in your Town Car. Iridium offers enhanced longevity and superior performance stability over platinum or copper. As long as the heat range and thread specifications are correct for your 4.6L V8, iridium plugs are a beneficial upgrade.

How often should I replace the spark plugs on my Town Car?

The recommended interval depends on the type of plug you choose. Copper (V-Power) plugs should generally be replaced every 30,000 miles. Platinum and Iridium plugs can last much longer, typically between 60,000 and 100,000 miles, depending on driving conditions and plug brand.

Should I replace my ignition coils when I change the spark plugs?

It is highly recommended, especially on 4.6L V8 Town Cars with over 100,000 miles. The “coil-on-plug” (COP) system found in these cars means that a failing coil can quickly damage a new spark plug. Using a complete kit, like the ENA set with coils, ensures maximum ignition reliability.

Why are there two different NGK V-Power options for the Lincoln Town Car?

The two NGK V-Power options listed cater to different engine generations. The 5.0L V8 V-Power set is specifically for the older Town Cars (1986-1990), while the 4.6L V8 V-Power set covers the modern Modular engine generations (1991-2011). It is critical to confirm your engine size (4.6L or 5.0L) before purchasing.
