Air Box Mod on the 05 WR 450?

I've already removed the snorkel and cut holes in the right side of the airbox itself, but since this is covered by the right side number plate cover, not sure how much good this is actually doing? I have not been able to find any specifics here on what others may have done.

Thanks, Ron

I have a '06 did the same and believe this is correct. Lots of room around the number plate if you think about it.

Barnmpro airbox vent. for the left side.

The side plate isn't restricting airflow.
