Quick spark plug question

So I think I flooded my engine which prompted me to pull the plugs. I have wanted to do this since I bought the car a few months back but anyway I pulled them and they looked terrible. I noticed they were all bur 9's. In my other one I have bur 6 n 8's which are new. Should I just swap them or go get 7's and 9's or just all 9's. Ive read the threads on the differences but it still confuses me. So will my 6's and 8's be fine till I can get some new ones or should I just wait?

BUR9EQ's are a "colder" spark plug. If you're daily driving the car, then get the BUR7EQ for leading and BUR9EQ for trailing. Your fuel mileage will increase, driveability will improve, everything. Putting BUR9EQ's all around is pretty much what you'd want to do if you were running the car on the track at high RPM all the time.

I recommend reading Wikipedia's blurb about spark plugs. Very informative. Especially the part about "heat range", about 2/3 of the way down.

7's and 9's Make the SEVEN feel fine.
Honestly,just get 7's and 9's.It has been proven they work,why screw with other stuff?.
When you start skimping out on Parts for these cars,they will bite you in the ***.

Just got back from the parts store, I got the 7's and 9's and am happy about it lol. Hope she fires up when I put them in. I can't remember why I have 6's and 8's in my other car and I'm thinking it had something to do with the engine blowing up. I always ran the 7's and 9's before and had no problems. Hopefully im back on the right track.

Got the plugs in and all is well. At first I was worried cause it didn't fire right up and I could hear a strange clicking noise. After that I pulled the egi fuse and turned it over a couple times and tried again. Finally she started to sound like it was going to start and then did. I left a nice cloud of smoke in my neighborhood lol. I guess this is nothing new but figured I would share my experiences.
