Key Takeaways
- The EPAuto GP564, also known as CA9564, fits select Honda Accord L4 2.4L models from 2003-2007 and Acura TSX models from 2004-2008.
- Its 13.39 x 5.87 x 1.81 inch rigid panel design matches the factory-style airbox shape for direct installation.
- The paper-style filter media helps trap dust and road debris before air reaches your engine intake.
- The 12,000-mile replacement interval works for typical use, but dusty roads call for earlier visual checks.
- You should confirm your engine size and OEM cross-reference before ordering because fitment matters more than brand name.
What Is the EPAuto GP564 Engine Air Filter?
The EPAuto GP564 is a replacement engine air filter for specific Honda and Acura 2.4L applications. It sits in the factory airbox and replaces the old paper filter that screens incoming air before it reaches the engine.
The main appeal is simple: you get a budget-friendly maintenance part that uses the common CA9564 cross-reference. That makes it easier to compare against FRAM CA9564, Honda 17220-RAA-A00 style replacements, and other compatible aftermarket filters.
This is not a reusable oiled performance filter. It works best as a normal service item for drivers who want clean airflow, dirt capture, and a direct-fit replacement without changing the stock intake system.
Who Should Buy the EPAuto GP564?
Who It’s For
- Honda Accord L4 2.4L owners with 2003, 2004, 2005, 2006, or 2007 models who need a direct CA9564-style replacement.
- Acura TSX owners with 2004-2008 models who want a simple engine air filter for routine maintenance.
- DIY owners who prefer a fast airbox replacement instead of paying a shop for a basic filter change.
Who Should Skip It
- You should skip it if your Accord has a V6 engine because this listing targets the L4 2.4L application.
- You should choose an OEM Honda or Acura filter if you only want genuine factory-branded parts.
- You should look at reusable performance filters if your goal is washable media, not a disposable paper-style replacement.
EPAuto GP564 Design and Build
The EPAuto GP564 uses a rigid panel design with a pentagonal shape that matches the factory-style airbox layout for the listed Honda and Acura vehicles. Its listed size is 13.39 x 5.87 x 1.81 inches, so the outer frame must sit flat inside the airbox to seal correctly.
The filter weighs about 12.3 ounces, which suits a standard disposable engine air filter. You should not need special tools for most airbox checks, but the exact process depends on your vehicle’s clips, fasteners, and intake cover layout.
The key build detail is the seal around the filter edge. A good seal helps force incoming air through the filter media instead of letting dust pass around the frame, which matters more than the brand label on the package.
Filtration and Engine Protection
The GP564 filters incoming air before it enters the engine intake path. That job sounds basic, but it matters because dust, sand, pollen, and road debris can collect fast in daily driving.
A clean CA9564-style filter can support normal airflow in the stock intake system. It will not add performance like an intake upgrade, but it can help restore proper airflow when your old filter has become clogged.
You should treat fuel economy claims carefully. Replacing a dirty engine air filter can help your engine breathe better, but your mileage also depends on tire pressure, spark plugs, driving style, traffic, and engine condition.
Fitment for Honda Accord and Acura TSX
The main fitment group is Honda Accord L4 2.4L from 2003-2007 and Acura TSX from 2004-2008. That makes this filter most useful for owners maintaining older Honda K-series 2.4L vehicles.
You should still confirm your year, trim, and engine before buying. A 2003-2007 Accord V6 may use a different filter, so matching only the model name is not enough.
The CA9564 cross-reference helps you compare this EPAuto part against other filters. If your current filter or owner’s manual points to CA9564 or Honda 17220-RAA-A00 style fitment, this EPAuto listing becomes easier to check.
Installation and Airbox Seating
The EPAuto GP564 is designed as a direct drop-in replacement. You remove the airbox cover, lift out the old filter, clean loose debris from the lower airbox, and place the new filter in the same direction.
The most important step is seating the filter edge evenly. If one corner rides above the airbox tray, the cover can pinch the filter and leave a gap where unfiltered air may pass.
After installation, close the clips or fasteners fully and check that the airbox cover sits flat. A two-minute fitment check can prevent noise, poor sealing, and avoidable intake dust.
Fitment, Specs, and Performance Highlights
The EPAuto GP564 offers the right mix of low cost and practical fitment for specific Honda and Acura owners. Its 13.39 x 5.87 x 1.81 inch size, 12.3-ounce weight, and CA9564 cross-reference give you clear numbers to compare before ordering.
In normal use, the biggest benefit comes from replacing a dirty or collapsed filter. You may notice smoother throttle response if your old filter was heavily clogged, but you should not expect this part to transform engine power.
The service interval in the article is about 12,000 miles. For dusty roads, heavy pollen seasons, or construction-area driving, you should inspect the filter earlier and replace it when the pleats look loaded with dirt.
How It Performs in Real Use
For Daily Commuting
For daily commuting, the GP564 works as a simple maintenance part. If your 2.4L Accord or TSX still uses an old clogged filter, replacing it can help the intake system receive cleaner airflow during stop-and-go driving.
For Dusty Roads
Dusty roads shorten the life of any paper-style engine air filter. You should check the GP564 around 6,000 miles in dusty areas, then replace it before the pleats become packed with visible dirt.
For DIY Maintenance
This filter suits DIY maintenance because it uses the stock airbox location. You do not need to tune the car, reset electronics, or modify the intake system when the filter matches your vehicle.
Pros and Cons
Pros
- Confirmed CA9564-style fitment for select 2003-2007 Honda Accord L4 2.4L and 2004-2008 Acura TSX models.
- Direct drop-in design means you can install it without intake modifications.
- 13.39 x 5.87 x 1.81 inch size gives you clear measurements for pre-purchase checking.
- Works as an affordable routine maintenance part for older Honda and Acura vehicles.
- Disposable paper-style design keeps service simple because you replace it instead of washing and re-oiling it.
Cons
- It does not fit every Honda Accord, especially V6 models or trims outside the listed 2.4L range.
- Warranty details are not clear from the available product information, so you must check the listing before ordering.
- It is not washable or reusable like some performance filters.
Maintenance Schedule, Warranty, and Buying Tips
The recommended replacement interval is about 12,000 miles under normal driving. That interval works as a simple rule, but your real schedule depends on road dust, pollen, construction zones, and how often you drive.
You should inspect the filter around 6,000 miles if you drive in dusty or high-pollution areas. Hold it up to light and check the pleats for heavy dirt buildup, dark patches, leaves, or damaged edges.
Before buying, confirm the fitment against your vehicle year, engine, and old filter number. You should also check the current Amazon listing for return terms and warranty details because those terms can change by seller and marketplace.
Is the EPAuto GP564 Worth the Price?
The EPAuto GP564 makes the most sense as a value replacement part. You get a known CA9564-style fitment, clear measurements, and a simple install path without paying extra for a genuine dealer-branded filter.
It offers strong value for the price if your goal is routine maintenance. The best buyer is someone keeping an older Accord or TSX in good condition without overspending on a basic service item.
You should pay more for an OEM filter if factory branding matters to you. You should also consider a washable filter only if you want long-term reuse and don’t mind the extra cleaning process.
How It Compares to Alternatives
The closest alternative is the FRAM Extra Guard CA9564, which targets the same general Honda Accord and Acura TSX application. FRAM may appeal to you if you prefer a more widely recognized retail filter brand.
You can also compare it with a genuine Honda 17220-RAA-A00 style engine air filter if you want OEM fit and branding. The EPAuto GP564 remains a smart buy for everyday use when you want low-cost maintenance and verified CA9564 compatibility.
