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!
