Well, there are, or were two copy-cat filters, one of which made quite a production about how the bypass was removable. Their "fishing lure" was that the filter (not the cover, now) was available anodized in colors. So if that's not Ready, I stand corrected on that point. But the rest of my questions remain unanswered, don't they?
The bad info I was referring to was the statement about a removable bypass valve for cleaning and how it is a silly concept. Ready's bypass valve is not removable. Maybe you were thinking of another manufacturer?
Regarding the "trick" oil filter cover. If you can't recognize what is trick about a CNC machined billet aluminum part that is anodized black with an engraved logo, then the stock cover is definitely for you.
But maybe you can help me with the cover thing. What is "trick" about a filter cover that does nothing but add weight, is a different color than the rest of the engine, and bears the logo of a company that thinks disposable air filters are a good idea, so that everyone can see that I took the bait? Not everything that can be CNC'ed from billet stock should be.
