Is there any other place to buy a replacement for this Air Cleaner, besides HD?

It's the one that has a 90 deg on it but the compact version to use with lowers.

Thanks

 

The filter is a KN oil filter you do not replace it you wash and oil it.
Most will last a life time.
If your looking for an aftermarket that is cheaper to install one good luck most of them are cheap junk.
HD part number for the whole kit is 28716-10A
Replacement filter is 28714-10

 

Yes I bought the kit to clean it, and oil it...

I keep the rain sock on it all the time, you see a problem with this?

Thanks you

 

Only problem with keep the sock on all the time is it fades out in color.
The sock will help keep bugs off it also.
I keep the sock on all the time. However At time when I had if off in rain it was not an issue. It takes a major down pour to be a problem.
Some advice follow the direction for cleaning ,no need to do any more than it calls for and the filter will last a long time.
No need to over oil it.
