To find the correct oil filter, you should:
1. Check your owner's manual: This is the most reliable source. It will specify the correct oil filter part number.
2. Look up your VIN: Use your Vehicle Identification Number (VIN) on a parts website like Mopar (the Dodge parts website), AutoZone, Advance Auto Parts, or similar. Entering your VIN will ensure you get the correct part for your specific vehicle.
3. Check the oil filter itself: If you've changed the oil before, the old filter may have a part number printed on it.
Once you know your engine size, you can also search online using that information and "oil filter" for more specific results. However, using your VIN is always the most accurate method.
