I tested on the same spot today both of these. Originally I have the stage 2 Pro Dry S. So I bought the Pro 5R cone filter from amazon, which has a part number of 24-91031. The Pro Dry S has a part # 21-90045
Any here's a pic of the Pro Drys MAF test
Highest came out 386.9 g/s.
I then stopped and removed the Pro Dry S and placed the Pro 5R , and this is the result.
The difference is about 11g/s, having the Pro 5R with a higher number.
