I have a set of USDM air box lids with mass air flow sensors. These have had the plastic piece removed that hold the charcoal filters. No other modifications.

Whats the diff between these and the european ones

See how his velocity stacks are flat on the top to fit the charcoal filter? ROW do not use that filter so the velocity stack is completely round.

The ROW boxes make exactly 0 more horsepower. I dyno'd back to back. They did nothing at all on my car before the supercharger.

Well a friend was working his way through some bolt-ons for his P31 Development Package and dynoing each step of the way. He saw +5hp on 2 runs (Dyno Dynamics, HUGE fans) with the ROW boxes vs non-modified OE airboxes.

SO is the OP selling Row boxes or OE air boxes. I am confused

They are not row boxes that I'm selling. My dyno runs were also on a Dynamics. I have the row boxes on my car with the supercharger.
