My version of the classic "Gas, Ass, or Grass" saying on a round cover made specifically for the Harley Davidson Stage 1 air filter or the Vance and Hines stage 1 filter.
Will also work on other filters of that style as well. It measured 5.5" across and uses a 5/16" mounting bolt.
I sell them in Polish and Raw finish.
The Raw finish matches the HD stage one backing plate really well.
These will not always be available, I did one small run and will probably do one or two more tops.
