Finding your Wix filter model number using the Wix lookup tool

Wix makes oil filters for most vehicles, and the fastest way to find the exact filter your car needs is through the Wix Parts Finder on their website. You enter your vehicle's year, make, and model, and the tool returns the correct Wix filter part number — usually a four or five-digit code starting with 51 or 57. This takes about two minutes and removes the guesswork.

Go to wixfilters.com and click "Find a Filter" or "Parts Finder" (the exact button name changes occasionally, but it's always on the homepage). Select your vehicle information from the dropdown menus: year first, then make, then model. Some vehicles have multiple engine sizes, so you may need to pick that too. The tool will show you one or more Wix filter options — usually just one for your engine type.

Write down the part number exactly as it appears. This is what you'll use to order the filter, confirm it with a parts store, or check the shelf at an auto supply shop. The part number is more reliable than the filter's physical appearance, since Wix packages look similar across different models.

Key Takeaways

  • The Wix Parts Finder on wixfilters.com is the official source and takes two minutes to return your exact filter part number.
  • You need your vehicle's year, make, model, and sometimes engine size to get an accurate result.
  • Wix part numbers usually start with 51 or 57 and are four or five digits long — write this down before you shop.
  • If the Wix site is down or unclear, you can also call a local auto parts store with your vehicle information and ask for the Wix equivalent.

What to do if your vehicle doesn't appear in the Wix lookup

Older vehicles, commercial trucks, and some specialty engines sometimes don't show up in the standard Wix lookup. This doesn't mean Wix doesn't make a filter for your vehicle — it usually means the online tool has a limited database. Call Wix customer service at 1-800-558-5571 (available Monday through Friday, 7 a.m. to 5 p.m. Central time) with your vehicle's year, make, model, and engine size if you know it. They can tell you the correct part number over the phone.

You can also visit an auto parts store in person with your vehicle information. Staff at Advance Auto Parts, AutoZone, O'Reilly, or NAPA can look up the Wix filter in their system and either tell you the part number or show you the physical filter. This is often faster than waiting on hold, and you can see the filter before you buy it.

Using the part number to order or purchase your filter

Once you have the Wix part number, you have several options. You can order online from Wix's website directly, from Amazon, from Walmart, or from any auto parts retailer that stocks Wix filters. Most auto parts stores carry Wix filters in stock, so you can walk in, give them the part number, and leave with the filter the same day.

Prices vary by retailer and by filter type. A standard Wix oil filter usually costs between $5 and $15, depending on your vehicle and whether you choose a basic or premium filter. Wix makes several tiers — their basic filters are cheaper, and their synthetic or extended-life filters cost more but last longer. The Wix lookup tool will show you which types are available for your vehicle, so you can compare prices and decide which fits your budget.

Confirming you have the right filter before installation

Before you install the filter, check three things. First, compare the part number on the box to the number you wrote down from the Wix lookup — they must match exactly. Second, look at the filter's thread size (the part that screws onto your engine). It should match your old filter; if it looks different, double-check the part number. Third, check the filter's height and diameter against your old filter — they should be similar, though not always identical.

If something doesn't match, take the filter back to the store or contact Wix customer service before you install it. Installing the wrong filter can cause oil pressure problems or leaks, so it's worth the five minutes to verify.

Understanding Wix filter types and when to use each one

Wix makes several filter lines, and the Wix lookup tool will show you which ones fit your vehicle. Their basic line (usually part numbers starting with 51) is the standard choice for most vehicles and works well for regular oil changes every 3,000 to 5,000 miles. Their premium lines (often labeled as "XP" or with higher part numbers) use synthetic media and last longer — usually 7,500 to 10,000 miles — but cost more upfront.

For most drivers, the basic Wix filter is the right choice. If your vehicle's manual recommends synthetic oil or if you drive in severe conditions (towing, dusty roads, frequent short trips), a premium Wix filter may be worth the extra cost because it lasts longer between changes. The Wix lookup tool usually shows you all available options for your vehicle, so you can read the descriptions and decide which fits your driving.

What to do if you need a filter for an older or unusual vehicle

Vehicles older than about 1990, commercial equipment, motorcycles, and some imported cars may not appear in the standard Wix lookup. For these, call Wix customer service with as much detail as you can provide: the exact year, make, model, engine size (in liters or cubic inches), and the engine type if you know it (V6, inline 4, diesel, etc.). They maintain a broader database than the online tool and can usually find a match.

If Wix doesn't make a filter for your specific engine, they'll tell you directly. In that case, you can ask them to recommend a compatible alternative brand, or contact your vehicle's manufacturer or a specialty shop that works on that make. Some vehicles use filters that are specific to that manufacturer and don't have Wix equivalents.

Frequently Asked Questions

Can I use a Wix filter if my car's manual says a different brand?

Yes. Wix filters meet the same industry standards as other major brands, and as long as the part number matches your vehicle, it will work correctly. The manual usually lists one brand as an example, not as a requirement. Many mechanics and fleet operators use Wix filters as a direct replacement for other brands.

What if the Wix website is down or won't load?

Call Wix customer service at 1-800-558-5571 during business hours, or visit an auto parts store and give them your vehicle information. They can look up the Wix part number in their system. You can also search online for "[your vehicle year/make/model] Wix filter part number" — many forums and parts sites list these.

Do I need to know my engine size to use the Wix lookup?

Usually not — the lookup tool will ask for year, make, and model, and if there's only one engine option for that combination, it will show you the filter. If your vehicle came with multiple engine sizes, you'll need to pick the right one from a dropdown. Check your vehicle's door jamb sticker or owner's manual if you're unsure.

Is a more expensive Wix filter always better?

Not necessarily. A premium Wix filter lasts longer between changes, which saves money over time if you keep the vehicle for years. For a vehicle you plan to sell soon, or if you change oil frequently anyway, the basic Wix filter is fine. Check your vehicle's manual for the recommended oil change interval — that's the best guide for which filter tier makes sense.
