7's all around?
Ok, I just replaced my plugs and ordered 9EQ's from the parts store but recived 4 EQ's. Would I end up damaging anything by running th 7's all around only during the winter when starting my car once a week or so, and then for like 300 400 miles in the spring before I replace them?

The difference between 9's and 7's is the amount of heat they dissipate. 9's dissipate more heat than 7's. I personally wouldn't advise running all 7's. Here's a nice spark plug discussion that took place a few months ago: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/spark-plugs-500rwhp-347332/
