Now, with that said, before you spend any money, you need to see exactly what CFM worth of filter assembly you need to properly feed your engine.
Using the simple formula
A= effective filter area
CID=engine displacement
RPM=maximum RPM expected
Using the CFM formula of height X diameter x 6 x 3.14
Also keep in mind that the 14" extreme top flows 500cfm by itself.
Hope you find this helpful.

Bill -
Thanks for the info. As noted earlier, I got the R2C bottom plate with 14" x 3" filter.
As for your formulas, here is what I get:
468 x 5500/20839 = 123.5
3" x 14" x 6 x 3,14 = 791
I don't understand what the numbers are telling me, can you help?
