Maybe this is old news but I was at K&N's web site (www.knpowersports.com) and they listed part numbers for the Raptor. They are as follows:

Filter: YA-6601
Stage 1 Jet Kit: 81-Q414
Stage 1 Jet Kit w/ Filter: 23-Q414

There was no pricing that I could find but the do have a dealer locator option.

Sorry, I don't know how to make a hot spot for the web site so you'll have to copy & paste.

 

I know K&N shows a part number but I was told that they were having problems with it fitting right. My dealer said 8 weeks untill its out but I heard that in December.
