ok GM cars and old DSM had this type of thing in the MAF so it would read the right air flow amount. it is a minor restriction and good if your getting a CEL for airflow

It's been awhile, but we were getting less than desirable curves on dyno. Seems to improve linearity.

The BOV helps as well. Pure Tuning - Aaron, stated he's seen he same BOV in Subarus (same part) with eventual, inefficient performance. I'm currently using the "light" spring.

we cant run a standard BOV but we can run an aftermarket Bypass valve or recirculating valve. I know ken runs one without getting a CEL related to it at least.

That air straightener is definitely interesting. I've got a stage 2 Legacy GT and there's certain intakes to avoid because of turbulence across the MAF (Subaru in general). I'll definitely have to look into it and ask my tuner about it.
