How to Replace the Engine Air Filter on a 2019 Honda Accord

You can replace the 2019 Honda Accord’s engine air filter in about 5–10 minutes: open the hood, locate the air cleaner box on the driver’s side of the engine bay, release the spring clips (or remove the small fasteners, if equipped), lift the lid, swap in a new panel filter, and resecure the cover. This routine DIY helps maintain performance and fuel economy and is similar across the 1.5L turbo, 2.0L turbo, and Hybrid models, with only minor differences in fasteners and surrounding components.

What You’ll Need

Gather a few basic items before starting so the swap goes smoothly and you avoid damaging intake components.

• New engine air filter (OEM-equivalent panel filter matched to your engine: 1.5T, 2.0T, or Hybrid; verify by VIN)
• Clean shop towel or vacuum (to remove debris from the air box)
• Flathead screwdriver or Phillips screwdriver/10 mm socket (only if your air box uses a screw/bolt; many trims use tool-free spring clips)
• Gloves and safety glasses (recommended)

With the right filter and a couple of basic tools, the job is straightforward and requires no specialized experience.

Step-by-Step: Gas Models (1.5T and 2.0T)

These steps cover the most common setup on 2019 Accord gasoline models, which use an air cleaner box secured by spring clips and rear hinge tabs.

1. Park safely and let the engine cool. Turn the ignition off and open the hood using the interior latch and hood prop.
2. Locate the air cleaner box. It’s a black plastic box on the driver’s side of the engine bay with an intake hose and a sensor harness attached.
3. Release the cover. Unclip the spring clips at the front edge of the box. Some trims may have a small screw or 10 mm bolt—loosen it just enough to lift the lid. Do not unplug the mass airflow (MAF) sensor.
4. Hinge the lid up. The rear of the lid sits in tabs—pivot it upward and slightly back to create room. Avoid straining attached wiring.
5. Remove the old filter. Note its orientation, then lift it straight out. Wipe out leaves/dust in the lower box with a towel or carefully vacuum.
6. Install the new filter. Seat it flat in the lower box with the rubber gasket fully against the edges. Most panel filters are symmetrical; if marked with “airflow” arrows, point them toward the engine.
7. Re-seat the cover. Engage the rear tabs first, then lower the lid evenly. Make sure no wires or the intake hose are pinched.
8. Secure the cover. Snap the spring clips back in place (or snug the screw/bolt—do not overtighten). Check for uniform gaps; the cover should sit flush all around.
9. Final check. Start the engine. It should idle normally and show no warning lights. If anything seems off, shut down and verify the cover is sealed and the MAF harness is undisturbed.

Taking care to seat the filter flat and fully engaging the cover tabs/clips ensures a proper seal, preventing unfiltered air from bypassing the element.

Notes for the Accord Hybrid

The Hybrid’s engine air filter sits in a similar air box. Follow the same procedure, but ensure the vehicle is completely shut off (not in READY mode) and avoid touching any orange high-voltage cables. No high-voltage service steps are required for the engine air filter.

When to Replace and What to Watch For

Honda generally recommends inspecting the engine air filter around every 15,000 miles and replacing about every 30,000 miles (or sooner in dusty conditions). These signs suggest it’s time for a new one:

• Noticeable drop in fuel economy or throttle response
• Visible dirt, dark staining, or debris packed in the pleats
• Rougher idle or louder-than-usual intake sound
• Frequent driving on unpaved/dusty roads

Regular checks between oil changes can catch a clogged filter early, helping preserve performance and engine longevity.

Tips and Common Mistakes

A few simple practices will keep the job clean and prevent sensor or air leak issues after reassembly.

• Do not unplug or stress the MAF sensor wiring on the air box lid.
• Avoid oiled aftermarket filters that can contaminate the MAF; stick with dry paper OEM-equivalent elements.
• Make sure the rear lid tabs are seated before latching the clips, or the cover may look closed but leak air.
• Remove large debris from the lower box—don’t blow dust toward the MAF.
• Don’t confuse the engine air filter (under hood) with the cabin air filter (behind the glove box).
• If your box uses a screw/bolt, tighten just snug; overtightening can crack plastic.

Following these pointers reduces the chance of air leaks, check-engine lights, or premature sensor issues after the replacement.

Time and Cost

Most owners complete the change in under 10 minutes. A quality OEM-equivalent filter typically costs $20–$45. Dealership or shop replacement often runs $50–$100, largely for labor and markup.

Disposal

The old filter is generally disposed of as household trash. If significantly oil-soaked or contaminated, follow local waste guidelines. Cardboard framing may be recyclable in some regions if separated from the media.

Summary

Replacing the 2019 Honda Accord’s engine air filter is a quick, low-cost maintenance task: open the air box, swap the panel filter, and ensure the cover seals evenly. Done on schedule—about every 30,000 miles, or sooner in dusty conditions—it helps maintain smooth performance, fuel economy, and engine protection across 1.5T, 2.0T, and Hybrid models.
