The product was in great shape when delivered. Even though the package was thin as it is the delivery was made with card and all was well with product. The instructions were good to use and change in my car. Also it showed the make of vehicle so I won’t be confused at all. Overall it was a great buy

Fits my Accord perfectly!

Size: 8.8" x 9.3" x 1.2"

Fits my 2008 Accord perfectly and feels just as sturdy as the OEM I used before, which cost nearly twice as much. Plus, it includes activated carbon, something the OEM didn’t have.

Easy to do it yourself and save!

Size: 8.8" x 9.3" x 1.2"

One place wanted $85 to replace this! Another wanted $50! I ordered this for $10, watched a YouTube video and did it myself! Super easy!
