The correct oil filter for a 2011 Honda Accord depends on which engine you have: the 2.4-liter inline-4 or the 3.5-liter V6. For the 2.4L, use Honda Genuine oil filter 15400-PLM-A02; for the 3.5L, use Honda Genuine oil filter 15400-PRB-A01. Always double-check with your VIN or owner’s manual to be sure.
In 2011, Honda offered two engine options in the Accord. Each engine has a specific oil filter that ensures proper oil flow and filtration. This guide explains the two engine variants, lists reliable filter options (including OEM and aftermarket choices), and provides steps to verify the correct part for your car.
Engine options in the 2011 Accord
Identifying the correct filter starts with identifying the engine. Below are the two configurations that were available for the 2011 model year:
- 2.4-liter inline-4 engine (most common in LX, EX, and Sport trims).
- 3.5-liter V6 engine (found in EX-L and some higher trims).
Knowing which engine you have helps you locate the right Honda Genuine filter and any compatible aftermarket options.
Recommended oil filter options
Below are the typical choices that fit the 2011 Accord, including the OEM Honda filter and widely used aftermarket alternatives. Always verify the fitment with your VIN or by checking the owner’s manual before purchasing.
- Honda Genuine Oil Filter for the 2.4L engine — 15400-PLM-A02
- Honda Genuine Oil Filter for the 3.5L engine — 15400-PRB-A01
- Quality aftermarket filters (cross-references exist for both engines). When shopping aftermarket, look for filters that list compatibility with Honda/Acura 2.4L or 3.5L engines and confirm thread size and gasket specs with the seller.
In practice, many drivers choose a reputable aftermarket filter that explicitly lists compatibility with the 2011 Accord’s engines. If you’re unsure, sticking with the OEM part numbers above or using a trusted aftermarket filter from brands like Wix, Bosch, Mann, Purolator, or K&N—and then confirming fit with your vehicle’s details—helps ensure proper filtration and oil flow.
How to verify the right filter for your car
To avoid wrong parts, use one of these verification methods:
- Check the engine type on your vehicle (2.4L I4 or 3.5L V6) and match it to the appropriate OEM part.
- Consult the owner’s manual or a Honda parts lookup using your VIN to confirm the exact filter number.
- If you’re buying aftermarket, bring the old filter to the parts counter or provide the exact engine and year so the staff can confirm cross-compatibility.
Accurate verification helps prevent ordering mismatches, especially if the car has been serviced in a different region or has an updated OEM part revision.
Maintenance tips and notes
Along with selecting the right filter, follow these tips to maximize filter effectiveness and engine longevity:
- Use the recommended oil viscosity for your climate (commonly 5W-20 for many 2011 Accords, though regional specifications may vary).
- Replace the oil filter every time you change the oil, typically every 5,000–7,500 miles (or per your owner’s manual) when using conventional oil; intervals may extend with synthetic oil.
- Inspect the drain plug gasket and the filter gasket during every change; replace gaskets if they show wear or cracking.
A correctly chosen filter paired with the right oil and maintenance schedule helps protect the engine from contaminants and ensures consistent oil pressure.
Summary
For a 2011 Honda Accord, the key is engine identification. The 2.4L four-cylinder uses Honda Genuine oil filter 15400-PLM-A02, while the 3.5L V6 uses Honda Genuine oil filter 15400-PRB-A01. If you prefer aftermarket options, use filters from reputable brands and verify compatibility with your specific engine and VIN. Always consult your manual or a parts specialist to confirm the exact part number before purchase.
