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. 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? 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.
