Boss vs Ultra.... should be interesting UOA/PC comparisons. We also have the synth filters from Amsoil, Wix, RoyalPurple, Bosch LL .... to compare also. Competitive market is a win for ...
The Boss shows a plastic mesh, and Frantz TP filters did have a support screen. Stainless steel mesh wears better, just like the metal end caps and center tube wear better, so it is superior. According to mann-hummel logic. It's superior to plastic mesh in other obvious ways. SS is more expensive and costly to manufacture, making the Fram Ultra a bargain.
