It might turn higher RPM but 7500 is plenty for me.
though, wouldn't a less restrictive air filter be one that does less filtering..
fyi, the reverse air ram works for the same purpose, not sure which one would end up providing less protection though.

also i personally rather do it this way so that when i find or make a nice looking scoop, i can take advantage of a much larger main jet.
And despite what others may say, i find it provides the extra air at any speed ive needed it,
cuz Ive never even approached 70 and it works for fine for me...

So as soon as you put any filter back on your numbers will go back down a bit, currently i wind out at 7k but my analog tach is a piece of crap, don't know if it can be trusted. that said, what do you tend to idle at? Mine says 2k.
