RC, is the ultra250 pro series power filter kit legal to be used in ijsba limited class? i heard its just for the open class. is that true? Thanks.

My interpretation has always been if the rules don't say you can do it, don't. The rules do not state that you are allowed to modify the hood. The stock glove box, which is part of the hood, must be modified to accommodate our Pro-Series Power Filter Kit.

I would write to the IJSBA for exact clarification on this though.
