Hey there...I just checked my spark plugs and the tips that are meant to spark are charred...still strong and in the correct shape, but black as night!

Is this normal? I don't know much about them.

they should be brown/gray/tanish color. Check your gap, or just replace them if it's been a while. If you do replace, get a double platinum of some sort. You don't have to worry about the gap on those. I use Bosch Plat2's but I think I'm going to switch to NGK's soon.
