ITESIER Engine & Cabin Air Filter Set for 2014–2018 Silverado/Sierra 1500 — OE Fit, 2‑Pack

These two replacement filters — one engine air filter and one cabin air filter — are manufactured to match OE fit and function for many Chevrolet Silverado, GMC Sierra and full-size SUV models. Built to the dimensions and specifications that align with listed OEM part numbers, the pair helps keep engine intake clean and cabin air fresher by trapping dust, pollen and common road contaminants. Fitment is specific: confirm your vehicle year, make and model against the compatibility list before ordering.

Which vehicles and engines will these filters fit?

The ITESIER filter pair was produced to fit a wide range of GM trucks and SUVs from model years 2014–2020, but not all engine types. It is compatible with most gasoline-powered 5.3L/6.0L configurations listed for Silverados, Sierras, Yukons, Tahoes, Suburbans and Escalades. Do not use these filters for 6.6L Duramax diesel engines.

• Silverado 1500 (2014–2018) and Silverado 1500 LD (2019)
• GMC Sierra 1500 (2014–2018) and Sierra 1500 Limited (2019)
• Tahoe, Suburban, Yukon, Escalade models (selected 2015–2020 years)
• Not compatible with 6.6L Duramax diesel models

How do these filters protect my engine and HVAC system?

The engine air filter reduces abrasive particles reaching the intake, which helps maintain combustion efficiency and throttle response over time. The cabin filter intercepts dust, pollen and road debris before they enter the passenger compartment, helping the HVAC system run more cleanly and preventing odor- and dust-related buildup.

• Engine filter media captures fine particulates to prevent internal wear
• Cabin filter screens pollen and common allergens for cleaner cabin air
• Proper filtration helps sustain factory fuel economy and performance
• Fits to factory mounting points for secure, leak-free installation

What are the installation and part-number details?

Both filters are manufactured to match OEM dimensions and provided with equivalent part number references to aid compatibility checks. Installation is a simple service task: the engine filter sits in the airbox while the cabin filter fits behind the glove box or HVAC access panel depending on the model year.

• Engine OEM references: 2845992, FSA8755A, FDA8755A, CA8755A, CAP8755A
• Cabin OEM references: 23281440, WP10129, PA4486, CF11809, CAF1914P
• Standard hand tools required; no modifications needed
• Follow vehicle service manual for access and replacement intervals

When should I replace these filters and what maintenance helps performance?

Replacement intervals vary by driving conditions; inspect the filters at routine service intervals and replace when visibly dirty or according to the owner’s manual. Harsh driving environments — dusty roads, heavy pollen seasons, or towing — may require more frequent changes to protect engine and cabin air quality.

• Check filters at every oil change or seasonal service
• Replace earlier if filters show heavy discoloration or blockage
• Keeping the airbox and filter housings clean extends filter life
• Use manufacturer-recommended intervals as a baseline

Who this is for: The ITESIER Engine & Cabin Air Filter set is intended for owners of compatible Chevrolet and GMC full-size trucks and SUVs who want a direct-fit replacement that matches OEM dimensions and referenced part numbers. It’s a practical purchase for DIYers, fleet managers, and technicians seeking dependable filtration that restores airflow and cabin comfort without complicated installation. Before purchasing, confirm your vehicle’s year, model and engine to ensure correct fit, particularly if your vehicle uses a 6.6L Duramax diesel (these filters are not for that engine).
