Just think about the dynamics of it for a moment.
The "spiraled air" must go through the 90 degree bend into the Throttle body. Let's just give them the benefit of the doubt and say it can manage that.
Then it gets cut in half by the throttle body butterfly. Let's give them the benefit of the doubt and say it splits off into 2 perfect sub spirals.
Then those 2 perfect sub spirals magically combine back into one spiral on the other side of the throttle body?
Then it is supposed to split up into 4 smaller sub spirals to head down each inake runner?
Those 4 smaller sub spirals then stay perfect through a 180 degree curve of intake manifold runner?
They then get blasted by 44 PSI fuel injection...
then they squeeze through a .044" opening to enter one of your two intake valves (or split the spirals AGAIN to enter EACH intake valve).
Then they keep spiraling around inside the combustion chamber till the pistion squishes them and the spark plug ignites the air fuel mixture.
Do you really think a cheap $0.99 piece of bent tin can accomplish all that? If so, why has no major auto manufacturer copied the design or bought the rights to these devices? Why do you not see them used in drag racing, NASCAR, and INDY cars?
Why? because they don't work.
In regards to cutting the GRILL off your MAF. Don't do it.
That "grill" is there to straighen out the air flow so that the MAF can get an accurate reading. Without the Grill there, turbulent air is allowed around to flow sometimes around the MAF element, sometimes over the MAF element. This causes erratic MAF readings, and a poor running engine.
I know this because I too cut the grill off my MAF way back when. After getting my OBD-ii cable, and doing lots of CAI testing, I finally got my hands on a new MAF with the grill. The air flow readings stabalized with the grill, and the car ran MUCH better.
