Hi
I am redoing the OEM filters on my '79 XS400 and need to replace the foam around the element. Does any one know what the rating of this foam should be?
The suppliers say it could be anything from 10 to 80 PPI where type 10 has large cells and is very open whereas PPI 80 has small cells, is more dense and has a lower air flow.
Your help is appreciated.
Thanks
