WHEELZEN Engine, Cabin & 2 Oil Filter Kit for Hyundai Sonata / Kia Optima 2011–2015 — OEM-Fit, Activated-Carbon Cabin

WHEELZEN’s complete filter kit replaces engine, cabin, and oil filters in one service — engineered to match OEM part numbers for 2011–2015 Hyundai Sonata and Kia Optima models.

If you own a 2011–2014 Hyundai Sonata (2.0T or 2.4L) or a 2011–2015 Kia Optima (2.0T or 2.4L), this all-in-one service pack gives you the engine air filter, activated-carbon cabin filter, and two oil filters needed for a routine maintenance stop. The set is built to fit the factory housings and to meet the replacement numbers listed by manufacturers, simplifying parts selection and cutting time at the garage.

Which factory part numbers does this WHEELZEN kit replace?

This kit cross-references a broad list of OEM and aftermarket numbers so you can be confident it matches the parts your vehicle requires. It covers multiple equivalent part IDs used by Hyundai, Kia, and filter vendors.

• Engine & cabin references: 281132P000, 281132P100, 281133S100, 28113-2P000, 28113-2P100, 28113-3S100, CA10881
• Oil filter equivalents: 97133-3SAA0, 97133-A9000, 971333SAA0, 97133A9000, CF11819
• Additional engine air numbers: 26300-11100, 26300-35503, 26300-35504, 26300-35505 and numeric variants

How will this kit affect engine breathing and oil protection?

The engine air filter element traps debris before it can reach the intake, helping the engine run cleaner between services, while the oil filters remove contaminants from the lubrication circuit to protect moving parts. These are not performance upgrades but maintenance-grade replacements designed to restore factory filtration.

• Engine filter: pleated media to capture dust and road debris
• Cabin filter: activated carbon layer reduces odors and particulates
• Oil filters (2): designed to fit factory mounting and maintain oil flow
• OEM-fit form factor ensures proper sealing and easy installation

Is installation difficult and what tools are required?

The set is intended for quick replacement with no modifications required. Basic hand tools and a few minutes of time are enough for most DIYers; service shops can swap all components during a standard oil and filter change.

• Engine air filter: clips or screws typically release the airbox lid
• Cabin filter: glovebox or cabin filter access panel removal may be needed
• Oil filters: use an oil filter wrench and follow safe oil-drain procedure
• Installation guide: check factory manual for model-specific steps and torque specs

Which models and years will this filter kit fit?

The kit is specially selected for the listed model years and engine types; verify fitment with your VIN or factory part numbers before purchase. It was packaged to match common configurations used in these Hyundai and Kia vehicles.

• Hyundai Sonata 2011–2014: L4 2.0L Turbo and L4 2.4L
• Kia Optima 2011–2015: L4 2.0L Turbo and L4 2.4L
