The forms "much impact" and "much of an impact" are essentially synonymous. "Of an" is added almost solely for emphasis and flow, but, semantically, it doesn't do a whole lot for the sentence other than make it longer and slightly verbose. Regardless of whether this can be considered proper usage, both forms work, and both forms are extensively used.
