Perfect fit!
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This is a good value for a combo package which includes a cabin air filter as well as the engine air filter. Both filters were a perfect fit in my 2019 Honda Accord hybrid. The cabin air filter airflow direction is clearly labeled and the pleats are sturdy. Installation was super easy- just drop the glove box cover, pop the cabin filter cover plate, pull out the grungy old filter and pop in the new one. Easy peasy. The engine air filter is also a perfect fit. No complaints or concerns here.

Perfectly Fine and Inexpensive
This off-brand filter was $10 cheaper than the local auto store, nearly $20 cheaper than the dealership, and meets the original OEM requirements. My husband is an ASE certified master technician and does all of our car maintenance and repair work himself and purchasing this filter rather than getting the filter from the dealership or the local auto store saved us a good bit of money and it is the same quality. Just make sure that the OEM number is correct for your vehicle and you have nothing to worry about.

Easy to install
Very easy to install this engine filter and checking the compatibility with my car was super easy too. I took me about 5 minutes to look up, learn, and install this. Loved that I saved money by installing it myself instead of getting overcharged but the shop. Works for a 2017 Honda Fit.
