67olds, you know that little filter on the tbi ring is a good idea but you don't need it, you can cap that nipple off, and what it needs is the filter in the valve cover or a reg. breather cap. That unfiltered air gets in the crankcase and turns the oil bad or more acidic or something.

Really as far as that goes that tbi spacer ring doesn't even need to be on there with that air cleaner, it should clear everything fine without it and free up the air flow to the injectors at the same time. Just need the offset stud or cut the stock one down to work with your air cleaner. That style is terrible for coming apart and falling into the motor.
