Ford Maverick Spark Plug Replacement Guide for 2022-2024 Models
Keep your Maverick's EcoBoost or Hybrid engine running strong with the right set of spark plugs.
- The official 100,000-mile replacement interval is often too long; consider changing plugs every 50-75k miles (or 30k if tuned) to maintain performance.
- High-quality aftermarket iridium plugs from brands like NGK and Denso are excellent alternatives to OEM Motorcraft plugs.
- Always verify the correct part number for your engine (2.0L EcoBoost vs. 2.5L Hybrid) as they are not interchangeable.
- Before installing, double-check that the spark plug gap is set to your engine's specific requirements to prevent misfires.
Signs of Failing Spark Plugs in Your Maverick
When spark plugs wear out, they can't create a strong enough spark to ignite the fuel mixture properly. This is called a misfire. You'll notice several signs when your Maverick's plugs are due for a change.
- Rough Idle: The engine may shake or vibrate more than usual when you're stopped.
- Poor Acceleration: The truck may feel sluggish or hesitant when you press the gas pedal.
- Reduced Fuel Economy: You'll find yourself filling up the gas tank more often because the engine is burning fuel less efficiently.
- Check Engine Light: A misfire will almost always trigger the check engine light. The most common code is P0300 for a random misfire, but you might also see codes P0301 through P0304, which point to a specific cylinder.
- Difficulty Starting: A weak spark can make it harder for the engine to turn over, especially in cold weather.
Choosing the Right Aftermarket Spark Plugs
The Ford Maverick uses modern iridium-tipped spark plugs from the factory for a long service life. When shopping for replacements, you have excellent options from both OEM and aftermarket brands. Unlike some parts, high-quality aftermarket spark plugs from reputable brands are just as good, and sometimes better, than the original Motorcraft plugs.
OEM vs. Aftermarket Quality
Motorcraft (OEM): These are the plugs your Maverick came with. They are high-quality iridium plugs designed to last. You can't go wrong with a direct OEM replacement. The OEM part number for the 2.0L EcoBoost is typically CYFS-12Y-RT3, and for the 2.5L Hybrid, it is AYFS-32Y-RX.
Top-Tier Aftermarket (NGK, Denso): These brands are often the original manufacturers for many car companies, including Ford. NGK and Denso Iridium plugs are considered an equal or even superior choice. For tuned 2.0L EcoBoost engines, many owners choose one-step-colder NGK plugs to handle the extra heat and prevent detonation.
Quality Aftermarket (Bosch): Bosch is another trusted German brand that produces high-quality Double Iridium and Platinum plugs that are a reliable choice for a stock Maverick.
Standard/Budget Aftermarket (Autolite): Autolite offers more budget-friendly platinum and copper plugs. While functional, they may not have the same performance or long lifespan as the iridium plugs your Maverick was designed for, potentially requiring more frequent changes.
A Note on Spark Plug Gap
Always check the spark plug gap before installation, even if the box says they are 'pre-gapped'. The gap is the distance between the two electrodes at the tip of the plug. An incorrect gap can cause misfires. For the 2.0L EcoBoost, the gap should be around 0.028–0.031 inches. For the 2.5L Hybrid, it's larger, around 0.049–0.053 inches.
Known Issues, Recalls, or TSBs
As of early 2026, there are no active recalls or widespread Technical Service Bulletins (TSBs) specifically for spark plug or ignition coil failure on the 2022-2024 Ford Maverick. While recalls exist for other components like the Body Control Module and Powertrain Control Module, the core ignition system has proven reliable.

Frequently Asked Questions
How often should I change the spark plugs on my Ford Maverick?
Ford's official maintenance schedule says to replace the spark plugs at 100,000 miles. However, many experienced technicians and owners of EcoBoost engines recommend a shorter interval. For the 2.0L EcoBoost, changing them every 50,000-75,000 miles can help maintain peak performance and fuel economy. If your engine is tuned, the interval should be even shorter, around 30,000 miles.
Is it hard to change the spark plugs myself?
For most DIY mechanics, this is a very manageable job. Both the 2.0L and 2.5L are inline-four engines with the spark plugs and coil packs easily accessible on top of the engine. You will need a basic socket set, a torque wrench, a spark plug socket, and a gap gauge. The job typically takes about an hour.
🎬 Watch this step-by-step guide to changing plugs on the 2.0 EcoBoost.Do I need special spark plugs for the EcoBoost or Hybrid engine?
Yes, you must use plugs specified for your exact engine. The 2.0L EcoBoost and 2.5L Hybrid use different spark plugs with different heat ranges and gap settings. Using the wrong plug can cause poor performance and even engine damage. Always verify the part number fits your specific engine before buying.
What are 'one step colder' spark plugs and do I need them?
A 'colder' spark plug is designed to dissipate heat more quickly from the combustion chamber. For a stock Maverick, you do not need colder plugs. However, if you have modified your 2.0L EcoBoost with an aftermarket engine tune that increases horsepower, colder plugs (like the NGK 6510) are highly recommended to prevent engine knock and potential damage.
