Convenient and Cost-Effective Air Filter Set for Gasoline Engine
Size: CRV (2023-2025) 1.5L Gas, Size: CRV (2023-2025) 1.5L Gas
Why did you pick this product vs others?: The set includes both the engine air filter and the cabin air filter, which I find extremely convenient because both usually need replacing around the same time—especially if you drive in dusty environments or have seasonal allergies. Ease of installation: I replaced both filters myself in under 20 minutes using just basic tools. No instructions are included, but a quick search online brought up several helpful videos tailored to my car model. Both filters fit perfectly without any force or trimming needed, which isn’t always the case with aftermarket brands. Functionality: From past experience, replacing the engine air filter regularly (every 12,000 to 15,000 miles as suggested in the owner’s manual) helps maintain better fuel efficiency and extends engine life by keeping debris out of the combustion chamber. After swapping in the new filter, I noticed the engine ran slightly smoother—especially on acceleration. Smell: The cabin air filter is equally important, particularly for passengers with allergies or sensitivity to airborne particles. I could immediately tell the airflow from the vents was stronger and fresher-smelling after the replacement, which suggests the old filter was overdue. Value for money: The ITESIER Cabin and Engine Air Filter combo pack is a smart buy for anyone maintaining a gasoline-powered vehicle like my Honda Civic. This combo pack offers good value for money compared to buying each filter separately. Quality: Overall, if you’re comfortable with basic DIY car maintenance, this kit is a great choice. It’s affordable, fits properly, and provides an easy way to knock out two important maintenance tasks in one go. Filter quality: The filters are high quality. They work without problems. Just be aware that this is designed only for gasoline engines—it won’t be compatible with diesel or hybrid powertrains.

Exactly what I needed
Size: CRV (2023-2025) 1.5L Gas
I'm not sure how much there is to say about an automotive cabin air filter. I double-checked the specs to make sure this was compatible with my car, ordered the filter, then installed it. It fit, it didn't have a weird smell, I haven't thought about it since. That's exactly what I want in an air filter. Five stars!

A perfect fit.
Size: 26" 26" 13"
It's not often you get to say 'perfect' about almost anything, but this is one of them. The product was a terrific price, it came in a day, was packaged perfectly, was easily removed from clever packaging, it was simple and obvious how to install, and it fir perfectly, both front and back. True OEM fit, feel, and finish. Like I sad, peeerfect for my VW Touareg. As advertised. 5-star. And I ask again, how many 5-star ratings have you given? This is my first and I'm n old guy. Been doing business on Amazon for decades.
