Not dumb, but quality of caps runs from stout to sketchy. ACD used to be id'ed by the yellow resin, and harder tensile plastic that appeared it would resist better from deflecting into the rotor if the vent harness is the least bit clogged, and round plug posts v. skinny little flat tabs. I used to try to keep straight on here whether Accel or MSD was having the quality issues, but it seems the negative rep was/is a moving target between those two. The quality likely moves around to reflect each aftermarket maker's warranty returns and then shoring up whatever weak point to make their unit barely passable. I can tell you the '15 vintage Spectra the prev owner installed has caps are FTL. But, there's got to be a new 'worst ever' out there by now to replace it.
