What the Wix Filter Finder does and how to access it

The Wix Filter Finder is an online tool that matches your vehicle to the correct oil filter part number based on your engine's specifications. Instead of guessing which filter fits your car, you enter your vehicle information—year, make, model, and sometimes engine size—and the tool returns the exact Wix filter you need. This saves you from buying the wrong part or making a trip back to the store.

You can access the Wix Filter Finder on Wix's official website at wixfilters.com. Look for a section labeled "Find Your Filter" or "Filter Finder" on the homepage. The tool is free to use and does not require you to create an account or provide personal information beyond your vehicle details.

Key Takeaways

  • The Wix Filter Finder matches your vehicle year, make, and model to the correct Wix oil filter part number in seconds.
  • You can search by vehicle information, by existing filter part number, or by engine specifications depending on what information you have on hand.
  • The tool shows you the exact Wix part number, cross-reference numbers from other brands, and sometimes local retailer availability.
  • If the finder returns no results, your vehicle may use a non-standard filter or you may need to verify your engine size with your owner's manual.

Step-by-step: searching by vehicle year, make, and model

Start by selecting your vehicle's year from the dropdown menu. Then choose the make (Ford, Toyota, Chevrolet, and so on). Next, select the model from the list that appears. Some vehicles have multiple engine options, so you may see a fourth dropdown asking you to confirm engine size or displacement—this step is important because the wrong engine size will return an incorrect filter.

Once you have entered all required fields, click the search button. The tool will display the correct Wix filter part number, often alongside a product image and basic specifications like thread size and capacity. Many results also show cross-reference numbers—the equivalent part numbers from other filter brands—which can be useful if you want to compare prices across manufacturers.

Searching by filter part number or engine specs

If you already know your current filter's part number but want to confirm it or switch to Wix, you can enter that number directly into the finder. This is faster than entering vehicle information and works even if you are not sure of your vehicle's exact year or model.

Some versions of the finder also allow you to search by engine displacement (measured in liters or cubic centimeters) or by VIN (Vehicle Identification Number). The VIN option is the most precise because it pulls your exact factory specifications from the vehicle database. If your vehicle's year, make, and model are ambiguous or you own a vehicle with multiple engine options, using the VIN or engine displacement search can prevent mistakes.

Understanding the results and part numbers

Wix filter part numbers follow a naming convention that tells you the filter's specifications. A typical Wix oil filter part number might look like "51515" or "51515MP". The number itself identifies the filter type, thread size, and capacity. The letters at the end (if present) indicate special features—for example, "MP" may indicate a bypass valve or anti-drainback valve configuration.

The results page usually shows the filter's micron rating (how small the particles it catches are), thread size, and whether it has a bypass valve. If you see multiple Wix options for your vehicle, the differences are usually minor and relate to specific engine variants or model years. Wix's website typically recommends one primary option, which is the safest choice unless your owner's manual specifies otherwise.

What to do if the finder returns no results

If the tool shows no match, first double-check that you entered your vehicle information correctly. Year, make, and model must be exact—a typo or selecting the wrong generation of a model will produce no results. If you are certain your information is correct, your vehicle may use a filter type that Wix does not manufacture, or it may be a specialty or commercial vehicle.

In this case, consult your owner's manual for the original equipment manufacturer (OEM) filter part number, then search for that number on the Wix site or contact a Wix customer service representative. You can also take your vehicle's VIN to a local auto parts store and ask them to cross-reference it; they often have access to databases that cover a wider range of vehicles and filter types.

Cross-referencing Wix filters with other brands

The Wix Filter Finder often displays equivalent part numbers from other manufacturers like Fram, Motorcraft, and Bosch. This cross-reference information lets you compare prices and availability across brands without having to search each manufacturer's website separately. A Wix filter and its cross-reference equivalent are engineered to the same OEM specifications, so they perform identically.

Keep in mind that cross-reference numbers are not always exact matches in terms of features or construction. Some filters may have slightly different bypass valve settings or media materials. If you are switching brands, it is worth reading the product descriptions on both the Wix and competitor sites to confirm they meet your vehicle's requirements.

Using the finder when you have an unusual vehicle

Older vehicles, imports, and specialty engines sometimes present challenges for online filter finders. If you own a classic car, a commercial truck, or a vehicle with a non-standard engine swap, the finder may not recognize your setup. In these cases, you have two options: search by the engine's actual displacement and thread size if the finder offers that option, or contact Wix directly with your engine's specifications.

Wix maintains a large catalog that includes filters for older and less common vehicles, but their online tool is optimized for current and recent model year vehicles. A phone call or email to their customer service team can often resolve the search in minutes, especially if you can provide your engine's displacement, the current filter's part number, or a photo of your existing filter.

Frequently Asked Questions

Can I use the Wix Filter Finder on my phone?

Yes. The Wix website is mobile-friendly, and the filter finder works on smartphones and tablets. The dropdown menus and search function are designed to work on smaller screens, though you may find it easier to read the results on a larger display.

Does the finder show me where to buy the filter?

Some versions of the finder display local retailer availability or direct links to online sellers, but this varies by region and by which Wix website you are using. If the finder does not show retailers, you can take the part number to any auto parts store or search for it online to compare prices.

What if my vehicle has multiple engine options and I do not know which one I have?

Check your owner's manual or look at the engine bay for displacement markings. You can also provide your VIN to a dealership or auto parts store, and they will tell you your exact engine size. Once you know the displacement, you can search again or use the VIN search option if the finder offers it.

Are Wix filters the same as the filters my dealership sells?

Not always. Dealerships typically sell filters under the vehicle manufacturer's brand (like Ford Motorcraft or Toyota Genuine Parts), but many of these are manufactured by third-party suppliers including Wix. The cross-reference numbers on the finder will tell you if a Wix filter is equivalent to your dealership's part, but construction and warranty may differ slightly.

Can I search by my current filter if I do not know the part number?

If you have the old filter in hand, you can usually find the part number printed on the filter itself. Look for a number stamped or printed on the top or side of the filter canister. Once you have that number, you can enter it into the finder to confirm it or find equivalent options.
