This guide provides a complete, practical overview of the 2017 Ford Explorer air filter, detailing its function, how to recognize when it needs service, and clear instructions for checking and replacing it yourself, ensuring your SUV continues to run efficiently and powerfully.
Understanding the Role of the Air Filter in Your 2017 Ford Explorer
The internal combustion engine in your Ford Explorer requires a precise mixture of air and fuel to operate. The air filter's sole job is to clean the air entering the engine. It traps dirt, dust, pollen, and other airborne contaminants before they can reach the engine's combustion chambers. Clean air is essential for proper fuel burning. A clogged or dirty air filter restricts airflow, forcing the engine to work harder. This imbalance can cause incomplete combustion, leading to a buildup of carbon deposits on engine components. Over time, this increases wear on parts like cylinders and pistons. For the 2017 Explorer, designed for both daily commutes and family adventures, a functioning air filter is non-negotiable for maintaining the power and efficiency expected from this SUV.
Signs Your 2017 Ford Explorer Air Filter Needs Replacement
Recognizing the symptoms of a dirty air filter can prevent performance issues. The most common sign is a noticeable decrease in fuel economy. A restricted filter causes the engine to consume more fuel for the same power output, so you may find yourself visiting the gas station more often. Reduced engine performance is another key indicator. You might experience sluggish acceleration, especially when merging onto highways or climbing hills. In severe cases, the engine may hesitate or jerk during acceleration. A dirty air filter can also trigger the "Check Engine" light. The engine's computer monitors airflow, and a significant restriction can set off a diagnostic trouble code. Unusual engine sounds, such as coughing or popping noises, or black smoke from the exhaust during startup, can also point to a clogged filter. Finally, a visibly dirty or dusty air filter upon inspection is a clear sign it needs changing.
How to Locate and Inspect the Air Filter in a 2017 Ford Explorer
Inspecting the air filter is a straightforward task that requires no special tools. First, ensure the vehicle is parked on a level surface with the engine off and cool. Open the hood and secure it with the prop rod. The air filter housing is a large, black plastic box located on the driver's side of the engine compartment. It is connected to a large intake hose. The rectangular box is usually held together by metal clips or screws. Release the clips or unscrew the fasteners. Carefully lift the top half of the housing. Inside, you will see the rectangular air filter. Remove it by lifting it straight out. Examine the filter material, typically made of pleated paper with a rubber gasket around the edges. Hold it up to a bright light. If light does not pass easily through the pleats and the material is caked with dirt, debris, or appears gray or black instead of its original off-white color, it needs replacement. Also, check for any damage, such as tears or holes in the filter medium.
Selecting the Correct Replacement Air Filter for Your 2017 Ford Explorer
Choosing the right replacement is crucial. The 2017 Ford Explorer uses a specific air filter size and shape. The OEM (Original Equipment Manufacturer) part number from Ford Motorcraft is FA-1884. Using this ensures a perfect fit. However, many reputable aftermarket brands offer compatible filters. When selecting a filter, you will encounter two main types: standard disposable paper filters and performance-oriented reusable filters. Standard paper filters, from brands like Motorcraft, Fram, or Purolator, are affordable and effective for most driving conditions. They are designed to be replaced, not cleaned. High-performance filters, such as those from K&N, are made of cotton gauze and are washable and reusable. They may offer slightly improved airflow but often require special cleaning kits and may not filter as finely as paper in very dusty environments. For most 2017 Explorer owners, a high-quality paper filter is the most practical and cost-effective choice. Always verify the filter is listed as compatible with the 2017 Ford Explorer, regardless of engine option.
Step-by-Step Instructions for Replacing the Air Filter
Replacing the filter is a simple DIY project. Gather the new air filter, a screwdriver if your housing uses screws, and a rag for cleaning. Ensure the engine is off and cool. Open the hood and locate the air filter housing as described earlier. Release the metal clips or remove the screws securing the housing cover. Some models may have a wiring harness or hose connected to the cover; gently disconnect it if necessary. Lift the cover and set it aside. Remove the old air filter. Take this opportunity to wipe out the inside of the lower half of the air filter housing with a dry or slightly damp rag to remove any accumulated dirt or debris. Do not let any debris fall into the intake tube. Place the new air filter into the housing, ensuring it sits flat and the rubber sealing gasket is properly seated in the groove. The filter will only fit one way. Carefully lower the housing cover back into place. Reconnect any wires or hoses. Secure the cover by fastening the clips or screws. Ensure the housing is completely sealed; an improper seal allows unfiltered air to enter the engine. Close the hood. Start the engine and listen for normal operation. This entire process typically takes less than 10 minutes.
Common Mistakes to Avoid During Air Filter Service
Avoiding simple errors ensures the job is done correctly. A frequent mistake is not properly sealing the air filter housing after replacement. If the clips are not fully engaged or screws are not tightened, unfiltered air can bypass the filter, introducing abrasive particles directly into the engine. Always double-check that the housing is completely closed and secure. Installing the filter incorrectly is another error. The filter has a specific orientation; forcing it or having it sit crooked compromises the seal. Ensure the rubber gasket is flush with the housing base. Do not overtighten housing screws, as this can crack the plastic housing. When cleaning the housing, never use compressed air to blow debris deeper into the intake system. Use a rag or vacuum carefully. Using the wrong filter size or type can also cause problems. A filter that is too small will not seal, and one that is too large may not fit or could buckle. Always use a filter specified for your vehicle model year and engine.
Recommended Maintenance Schedule and Associated Costs
Ford's general maintenance schedule for the 2017 Explorer recommends inspecting the air filter at each oil change and replacing it as needed, typically between 15,000 and 30,000 miles under normal driving conditions. "Normal conditions" are defined as mostly highway driving in a dust-free environment. For "severe service" driving—which includes frequent travel on dusty, gravel, or salted roads, extensive idling, or regular short trips—inspection and replacement should occur more often, potentially every 10,000 to 15,000 miles. The cost of a standard replacement air filter is modest. An OEM Motorcraft FA-1884 filter typically retails between 20 and 35. Aftermarket paper filters from trusted brands can cost between 15 and 25. A high-performance, reusable filter like a K&N model represents a higher initial investment, often between 50 and 80, but includes a cleaning kit for long-term use. If you have a professional service the filter, labor costs are usually minimal, adding perhaps 20 to 40 to the part cost. Performing the replacement yourself saves this labor cost entirely.
Impact on Vehicle Performance, Fuel Economy, and Emissions
A clean air filter has measurable benefits. The most immediate effect is on engine performance. Proper airflow allows the engine to breathe easily, resulting in smoother idling, more responsive throttle input, and better acceleration. This is because the engine control unit can maintain the ideal air-fuel ratio. Fuel economy is directly influenced. The U.S. Department of Energy states that replacing a clogged air filter can improve gas mileage by up to 10%. For a vehicle like the Explorer, this translates to tangible savings at the pump over time. Emissions are also reduced. A clean filter promotes complete combustion, which minimizes the output of harmful exhaust pollutants like hydrocarbons and carbon monoxide. Furthermore, by preventing abrasive particles from entering the engine, a good air filter protects internal components like cylinder walls and sensors, extending the engine's overall lifespan and preventing costly repairs.
When to Consider Professional Assistance
While air filter replacement is simple, there are scenarios where seeking a professional mechanic is advisable. If, during inspection, you notice significant damage to the air filter housing, intake hose, or surrounding components, a professional assessment is wise. If you are uncomfortable performing any under-hood work or cannot easily locate the housing, a quick service visit is a good option. Mechanics can also perform a more thorough inspection of the entire intake system. If you experience persistent performance issues like rough idling or poor acceleration even after installing a new air filter, the problem may lie elsewhere, such as with a mass airflow sensor, oxygen sensor, or fuel system component. A certified technician has the diagnostic tools to identify these related issues. For owners who simply prefer a documented service history, having the filter changed at a dealership or repair shop provides a service record.
Frequently Asked Questions About the 2017 Ford Explorer Air Filter
Many owners have common questions. A frequent one is whether a dirty air filter can cause the "Check Engine" light to illuminate. Yes, it can. A severely restricted airflow can trigger codes like P0171 (system too lean) by confusing the engine's sensors. Another question is about the difference between the engine air filter and the cabin air filter. They are completely different parts. The engine air filter cleans air for combustion, as discussed. The cabin air filter, usually located behind the glove box, cleans air entering the vehicle's interior through the HVAC system. Both require separate replacement. Owners also ask if aftermarket filters void the vehicle warranty. They generally do not, as long as the filter meets or exceeds Ford's specifications and is installed correctly. The Magnuson-Moss Warranty Act protects consumers in this regard. Some inquire about oil-coated performance filters. These, like K&N filters, require a light coating of special oil after cleaning to trap particles. Over-oiling can damage the mass airflow sensor, so following instructions precisely is critical. Lastly, drivers wonder if a filter can be cleaned instead of replaced. Standard paper filters cannot; they must be replaced. Only filters specifically marketed as washable and reusable are designed for cleaning.
