DavesRsTurbo, get the K&N OFF an std airbox with panel filter ON and cut the front off it to open it up (where the circular hole is)
and if it's the old style scorpion, swap the backbox to mongoose or magnex, as the old tyle scorpion is restrictive (2.5" (std diameter) all the way through to the backbox, then 2" In the backbox (smaller than std diameter). That will be a better basis for more power.
