No screening at all. Seems this particular Hitachi sensor works well without. The same MAF was in my '08 corvette with no screens either.

Custom MAF is now at 2.39" and fuel trims at about -2% which is way closer than stock.

I'm sure the bigger tubing past the MAF has a plenum effect.

On A MAP sensor that islow mentioned, i'm curious about that statement. It's not in the intake tract that I have seen. Typical on turbo cars. N/A cars that use them do so to balance out variances in Barometric pressure IMO..it may be somewhere.
