today i did a compression test, when i pulled my new ngk iridium plugs out they were extremely black. only had them for 2 months. and my compression was 195, 190, 185, 180. but when i did it i forgot to remove the FI fuse. r these numbers good for a 94 GSR with 60000 miles ? and why is my plugs so black?

 

94 with 60k miles ....as long as your number are +/- 10 from eachother you should be good....but it should be higher in the 200-220 range.....
