Perfect Fit
The product arrived today and I installed it right away, no issues. The fit was perfect for my 2022 Civic Sport and the quality matches that of Honda OEM.

Great Value
Item came as described and fit perfectly paid the price I usually pay for the engine filter for both engine and cabin filter definitely would recommend.

Great little bang for buck and DIY savings from the Dealership Service DEPT
Easy to install and very simple to place into the correct compartments in the glove box and engine bay. Took maybe 15 minutes or less. Quality is great and the air in the cabin is so fresh now! The quality of the air filters is OEM+ which is great when trying to save some money and add value to the product. Fits perfectly in my 2020 Honda civic Sedan. Includes everything needed to replace both filters. Includes both cabin and engine air filter
