I have a promini air intake. I wanted to purchase a spare filter and was told they didn't stock them. I wonder if anyone knows the K&N size that would work? I am assuming they will have one. And yes I could take it off and measure it but it is hotter than Hades outside. Thanks for your help.

 

Just go to Napa, Auto Zone etc. In The air filter section their should be a K&N Book. It will list Vehicles & what K&N filter is correct for your Vehicle.
We have been using K&N filters for our vehicles for years. We just clean them & reinstall. Never have to purchase another Filter unless you change Vehicles.
