2.0 Air filter

It would be nice to know that a filter minder is needed with this filter. Very upsetting to me when I received mine.

4.0 Good Air Filter

I know it’s a good air filter, because it’s a K&N! Minus 1 star for no description telling me that I need to order a filter minder to install in the hole on the far end of the filter! Then of course the filter minder isn’t available for 1-2 months, so I can’t install the filter until I get it. K&N website description just needs a bit more detail.
