1. Check your owner's manual: This is the most reliable source. It will list the correct oil filter part numbers for your vehicle.
2. Look up your vehicle's specifications: Websites like your vehicle manufacturer's site or parts retailers (like AutoZone, Advance Auto Parts, etc.) allow you to search by year, make, and model to find compatible filters.
3. Check the oil filter itself: If you have an old filter, it might have the correct part number printed on it.
Simply knowing the Fram TG43 number isn't enough to determine engine compatibility. You need to cross-reference it with your vehicle's specific requirements.
