What a feeling! With the engine air filter changed, the engine was able to take deeper, longer breaths, eventually reaching that famous “runners high” you hear so much about. The new interior air filter changed the atmosphere into crisp, clean mountain fresh air, causing my passengers and me to spontaneously yodel with abandon. Here’s to believing!

Wasn’t green but confirmed with Ecogard that it’s the correct filter

Size: 8" x 10" x 2", Size: 8" x 10" x 2"

As the title says the filter wasn’t green this time (purchased 3 other times). I read off the numbers to Ecogard technical support and they said it was their filter and by the date code manufactured by a different factory. This one was grey/black with blue edge and you could tell there was charcoal embedded in it. Not sure if it will perform the same and smell the same, as I preferred the scent of the green one. The listing needs to be updated with the correct picture if the green isn’t made anymore.
