      2015 Civic
      Size fits properly on a 2015 Honda Civic SI sedan. Price could be a little cheaper for a non-OEM part.

      Excellent fit and great quality”
      This filter fit perfectly and was very easy to install. The quality feels solid, and it made an immediate difference in air flow. It’s a reliable replacement at a much better price than the dealer. I’ll definitely be buying this brand again for future changes.
