I think the photos speak for themselves but I reckon the mod greatly reduces the restriction to inlet airflow.

I was going to use a cone type filter (like UltraSlow & others) but when I couldn't find the part I tried to think of something else. Also with the cone I was a bit concerned about water soaking the filter.
I didn't want to cut the (expensive) Callaway air box top so I used thin steel strips to fix the K&N air filter to the base with very small nuts and bolts. This way I can still fit the top if I'm caught out in heavy rain.
Total cost of mod $3
