Choosing the Right Aftermarket Spark Plugs
For the 2020-2024 Lincoln Aviator's 3.0L EcoBoost engine, using a high-quality spark plug is crucial. The original equipment (OEM) plugs are made by Motorcraft, and they are typically high-quality iridium plugs designed for longevity and performance.
- NGK and Bosch: These brands are widely regarded as top-tier aftermarket options. They often manufacture the original parts for many carmakers. Their Iridium and Ruthenium plugs are excellent choices that provide performance and durability comparable to, or sometimes exceeding, the OEM Motorcraft plugs.
- Autolite and Champion: These brands offer dependable, quality spark plugs that are often more budget-friendly. Their iridium and double platinum options are suitable replacements that will restore performance on a vehicle with high mileage.
Pro Tip: The Aviator's engine is sophisticated. It is highly recommended to use Iridium spark plugs, as they are designed to handle the high-energy ignition and high-pressure conditions of a direct-injection, turbocharged engine. Cheaper copper or standard platinum plugs may cause performance issues and will not last as long.

Frequently Asked Questions (FAQ)
When should I replace the spark plugs on my Lincoln Aviator?
The manufacturer-recommended interval is typically around 100,000 miles. However, if you experience symptoms like rough idling, poor acceleration, or a decrease in fuel economy, you may need to replace them sooner.
Is it difficult to replace the spark plugs myself?
For a DIY mechanic with the right tools, it is a feasible job. However, accessing the rear spark plugs on a V6 engine can be challenging and may require removing other components like the intake manifold. You will need a torque wrench, spark plug socket, and extensions. If you are not experienced, professional installation is recommended to avoid damaging the engine.
Do I need to gap the new spark plugs?
Most premium aftermarket spark plugs (like NGK and Bosch Iridium) come pre-gapped for the vehicle. However, it is always a good practice to verify the gap with a feeler gauge before installation to ensure it wasn't altered during shipping. The correct gap for the 3.0L V6 is typically around 0.030 inches.
Should I replace the ignition coils at the same time?
It is not required, but it can be a good preventative measure, especially on higher-mileage vehicles. A failing ignition coil can cause similar symptoms to a bad spark plug. If you are paying for labor to access the plugs, replacing the coils at the same time can save you money in the long run.
