Stock airbox vs. replacement cone filter on an 05

I've been mulling over this for most of last night.

I have a CAI on the car, but i really don't want to be tossed into STS, since this only my second season, and I don't want to get my doors blown off.

Question is:

Is removing the big lunchbox of an airfilter from my 05 and replacing it with the CAI cone filter at the bottom of the MAF considered "changing the air filter element" that allows me to stay in H-stock, or would that still toss me into STS? (I'd be removing the whole CAI, and putting most of the stock intake back in, minus the lunchbox under the fender just for the event).

It just seems to me like a gray area, and just want to make sure I'm within the rules. I searched around and couldn't find any answers.

Well, I'll have to check the service manual to see how Ford labels the unit.

Do you have Kumho or Hoosier race tires for the appropriate stock class? If not, you are going to get your doors blown off anyway so you might as well leave it alone and stay in STS.

Sorry.

Here is the Rule from section "A" of 13.10 of the 2006 SCCA Solo Rule Book for the Stock Classes. Pay special attention to the 1st sentence.

13.10 ENGINE AND DRIVE TRAIN

A. The Engine air filter may be removed or replaced. A replacment element which is taller than standard may not be used to hold the air cleaner cover open. No other components of the air induction system may be removed, replaced or modified.

So seeing how out air filter is a big sealed box that can not be opened, You would have just replaced it. The only thing that would get you is the long tube that goes in the fender. Slide that back in there and you're back to a replacement air filter element. All other stock parts are still intact. That's my take on it.
