Great replacement filters
Every year I clean and rebuild many generators prior to hurricane season. Having these on hand along with spare fuel filters, fuel lines and several other spare supplies have been great to have on hand. These filters work great and function how they are supposed to. They do not restrict air flow and hopefully will last a good amount of time. Usually i will date them and replace them after a certain hour count or every two years. Thus far, I have had no complaints from others or myself.
