Really Geoffy? Rpt Really Geoffy? How ironic you read your message of indignation on that subject. Disingenuous much? - don’t bother answering, the question is rehetorical.

Oh, geez, not more angst ridden emotional diatribes 😫 from naysayers who can’t seem to come up with a single coherent counter-argument to the questions, (1) why are aftermarket fuses better than stock fuses?, (2) why are some aftermarket fuses better than others? or (3) why are fuses directional? One assumes the naysayers and self-appointed science defenders just like to hear themselves talk. Talking the talk but not walking the walk.
Oh Geoffy, everyone knows stock fuses are superior to boutique fuses.
