The 2011 Honda Accord uses a cartridge-style oil filter, and the standard replacement is Honda Genuine part 15400-PLM-A01. This applies to the common 2.4-liter and 3.5-liter engines in North American models; always verify the exact fit for your vehicle by checking your engine code or VIN.
Below is a detailed look at the filter type, how to identify the correct part, and how to replace it during an oil change.
Filter design and identification
Unlike the old spin-on oil filters, the Accord uses a replaceable cartridge inside a small housing. When you service the car, you replace the filter element (and the housing O-ring) rather than the entire canister. The filter is located in a housing mounted on or near the engine, and you access it by removing the housing cover.
Engine options and compatibility
For the 2011 model year, Honda offered the Accord with a 2.4-liter inline-four (K-series) and a 3.5-liter V6 (J-series). In most cases, both use the cartridge-style filter design, and the primary OEM replacement referenced by Honda is 15400-PLM-A01. If you’re unsure about the exact part for your engine code, check the old filter or consult the Honda parts catalog using your VIN.
Official part numbers and where to buy
To help you source the correct filter, here are the common options. The Honda Genuine option is widely used and recommended for reliability and fitment. Aftermarket cartridge filters are also available and can be compatible, but you should verify fitment for your specific engine code.
- Honda Genuine Part: 15400-PLM-A01 (oil filter element) — cartridge-style filter for 2011 Accord engines.
- Aftermarket cartridge filters: Various brands offer compatible filters for Honda 2.4L and 3.5L engines; confirm compatibility with your VIN/engine code before purchase.
When selecting a filter, ensure you also replace the O-ring on the housing and use the oil type and capacity recommended in your owner’s manual. Keeping the housing clean and inspecting for any leaks after installation helps maintain engine health.
How to replace the oil filter on a 2011 Honda Accord
If you’re performing the oil change yourself, follow these general steps to replace the cartridge filter. Always refer to the official service manual for torque specs and procedure details for your exact model.
- Warm the engine, then park on a level surface and engage the parking brake. Lift the front of the car if necessary and place it on jack stands.
- Drain the engine oil by removing the drain plug and allowing the oil to fully drain from the sump.
- Locate and remove the oil filter housing cover. Depending on your model, you may need a specific tool or socket to loosen the cover.
- Remove the old filter cartridge from the housing and discard it. Inspect the housing and O-ring for wear or damage.
- Install a new filter cartridge, lubricate the new O-ring with a little engine oil, and reinstall the housing cover. Tighten to the recommended torque in the service manual.
- Replace the drain plug if needed and refill the engine with the correct amount and grade of oil for your engine. Check the level with the dipstick after a short interval of running the engine and recheck once cooled.
- Start the engine, check for leaks around the filter housing, and take a short test drive. Recheck the oil level and top off if necessary.
Replacing the cartridge filter is straightforward and cost-effective, but the key is ensuring you have the correct part and properly reseal the housing to prevent leaks.
Summary
The 2011 Honda Accord uses a cartridge-type oil filter, with Honda Genuine 15400-PLM-A01 as the standard replacement. Confirm fitment with your engine code and VIN, since aftermarket options exist. When replacing, remember to change the housing O-ring and follow the service manual for torque and oil capacity to keep the engine well-lubricated.
