That's interesting. Pictures of intake?
It is reasonable to assume that bends in the piping can take out helmholtz resonations.

Also, williaty's discoveries don't apply for all MAF cars it seems either. Sometimes, it's inconsistent between cars. For the most part though, it does happen. However, it's only Will's car we have data from.

We need more cars to log and show. And for the most part, people have seen this happen.

The way people can get rid of them may be many. Especially for different years.
