I just installed a Sparks Racing "Supercharger" air filter kit (filter and aluminum filter bracket) in place of the stocker. I'm wondering if anyone else is using this setup and whether (and to what extent) they had to go up on their main and pilot jets. Currently I'm running the Sparks exhaust, 45 pilot, 175 main and NCVQ on the 4th clip. That jetting worked pretty well with the stock airbox/filter setup (possibly a bit lean on the pilot).

Does anyone have experience with this filter kit and jetting for it?

 

Call them, I am sure if they answer they will give you what you need.
