What Is the Air Filter Number for a 2013 Hyundai Elantra?

The most commonly used engine air filter for a 2013 Hyundai Elantra (2.0L or 1.8L gasoline engines in North America) corresponds to Hyundai’s genuine part number 28113‑3X000 (or superseding numbers), with widely used aftermarket equivalents including Fram CA10755 and K&N 33‑2472; however, the exact part can vary by engine, trim, and market, so verifying with the VIN or an online parts catalog is essential before buying.

Why the Exact Air Filter Number Can Vary

When drivers search for an “air filter number” for a 2013 Hyundai Elantra, they’re usually looking for either the OEM (original Hyundai) part number or a compatible aftermarket reference such as Fram, Wix, or K&N. While the 2013 Elantra lineup shares a common platform, there can be differences in air filter specifications depending on engine size, market (U.S., Canada, Europe, etc.), and body style (sedan vs. GT/hatchback). That’s why sources sometimes list different numbers for what seems like the same car.

The Most Common OEM and Aftermarket Part Numbers

Most U.S. and Canadian 2013 Hyundai Elantra models with the 1.8L gasoline engine use a rectangular panel air filter. Parts catalogs and online databases converge on a set of widely referenced numbers for this component. Below are typical numbers you’ll encounter when shopping for an air filter.

Typical Engine Air Filter Part Numbers

The following list highlights commonly referenced OEM and aftermarket part numbers for the 2013 Hyundai Elantra engine air filter, focusing on widely available options in the North American market.

• Hyundai OEM (genuine): 28113-3X000 (often cited for 2011–2013 Elantra 1.8L; may be superseded by an updated Hyundai number in some catalogs)
• Fram: CA10755 (popular retail option for the 2013 Elantra sedan 1.8L)
• K&N (reusable performance filter): 33-2472 (designed to fit the 2013 Elantra air box for 1.8L engines in many markets)
• WIX: 49161 (commonly cross‑referenced for this model year)
• Bosch: 5298 (listed for 2013 Elantra 1.8L in many parts databases)
• Beck/Arnley: 042-1805 (aftermarket filter that cross‑references the Hyundai OEM part)

These part numbers serve as the most frequently used references for a 2013 Elantra’s engine air filter, but buyers should confirm compatibility using their VIN or a trusted catalog before purchasing, especially outside the North American market.

Engine, Trim, and Market Differences

Not every 2013 Elantra is built exactly the same, and this can influence the correct air filter number. In many countries, the 2013 model year included sedans, hatchbacks (Elantra GT in North America, i30 in other markets), and sometimes different engines such as 1.6L gasoline or diesel units. Each may demand a slightly different air filter shape or specification.

Factors That Affect the Correct Air Filter

The following list outlines the main variables that can change which air filter number is correct for a specific 2013 Hyundai Elantra.

• Engine type and size: The 1.8L gasoline engine used in most North American 2013 Elantra sedans typically takes the 28113-3X000 style filter. Other engines—such as 1.6L gasoline or diesel units found in some international models—often require different part numbers.
• Body style: The Elantra GT (hatchback) and international variants like the i30 may use a different air box layout compared with the sedan, which can change the filter part number even within the same model year.
• Market/region: Hyundai sometimes assigns different part numbers for the same physical filter in different regions, or uses slightly different designs to meet local regulations or supply-chain choices.
• Superseded parts: Over time, Hyundai may replace an older part number with a newer one that is fully compatible. Online catalogs may show both the original and superseding numbers.

Taken together, these variables explain why a quick search can return more than one “correct” number for a 2013 Elantra, making verification by VIN or catalog lookup an important final step.

How to Confirm the Correct Air Filter for Your Car

Because part numbers can shift over time and differ by region, the most reliable way to find the right air filter number for your 2013 Hyundai Elantra is to cross‑check multiple sources. This reduces the risk of buying a filter that doesn’t seat correctly in the air box or fails to match your engine configuration.

Practical Steps to Verify the Part Number

The following steps offer a straightforward way to confirm the correct air filter number for your specific Elantra, using information already available to most owners.

1. Check your owner’s manual: Some Hyundai manuals list the OEM part number for the engine air filter or at least describe a service procedure that can be cross‑referenced with an online catalog.
2. Inspect the existing filter: When you remove the current air filter, look along the plastic frame for a printed, engraved, or stickered part number. This is often an OEM number that can be used to find replacements or equivalent aftermarket parts.
3. Use your VIN in an online parts catalog: Entering the Vehicle Identification Number (VIN) on Hyundai’s official parts sites or reputable aftermarket databases (RockAuto, major retailers, or dealer sites) will typically return the exact part number for your configuration.
4. Contact a Hyundai dealer parts department: Provide your VIN and ask for the engine air filter part number for your 2013 Elantra; the parts advisor can also tell you if the original number has been superseded.
5. Cross‑reference with brand catalogs: Once you have the Hyundai part number, use cross‑reference tools (Fram, Wix, K&N, etc.) to find compatible aftermarket filters that match your preferences for cost, performance, or reusability.

By following these steps, owners can move beyond generic search results and confidently identify an air filter that fits correctly and meets the manufacturer’s requirements for their specific Elantra.

Engine Air Filter vs. Cabin Air Filter

One recurring source of confusion is the difference between the engine air filter and the cabin air filter. Both are sometimes described simply as “air filters,” but they serve very different purposes and use different part numbers.

Understanding the Two Filters

The following list clarifies the distinction so that owners do not mistakenly purchase the wrong type when searching for a “2013 Elantra air filter number.”

• Engine air filter: Mounted in the engine bay, this filter cleans the air entering the engine for combustion. The part numbers discussed above—such as Hyundai 28113‑3X000, Fram CA10755, and K&N 33‑2472—refer to this component.
• Cabin air filter: Located behind or near the glove box, this filter removes dust, pollen, and other particles from the air that enters the passenger compartment. It has its own set of part numbers (for example, Fram CF10729 or Hyundai 97133‑3X000, depending on market), unrelated to the engine air filter numbers.
• Different service intervals: Cabin filters are often changed for comfort and air quality, while engine air filters are changed to protect performance and fuel economy. Mixing them up during purchase or service can lead to improper maintenance.

Recognizing that “air filter” can mean two distinct parts helps ensure that owners buy and install the correct component when maintaining their 2013 Elantra.

Summary

For a 2013 Hyundai Elantra—particularly the common 1.8L gasoline sedan in North America—the engine air filter is typically associated with Hyundai’s OEM part number 28113‑3X000, with well‑known aftermarket equivalents such as Fram CA10755, Wix 49161, and K&N 33‑2472. However, variations in engine type, body style, and market mean the only fully reliable method is to confirm the part using the vehicle’s VIN, the existing filter’s markings, or an official parts catalog. Distinguishing clearly between the engine air filter and the cabin air filter further prevents mix‑ups and ensures the correct component is replaced during routine maintenance.
