The P.O. didn't go through the trouble of removing the radiator to change the front plugs, so he changed the rear plugs out for Champions (I know, wtf was he thinking???). The front plugs were the ORIGINAL NGKs, with 30k on them lol.
The Champions were anything but "champions", both were trashed. The NGKs weren't much better, but they still functioned somewhat (sparked every time, which the Champions did not), though the gap was very far off.
OBVIOUSLY, the P.O. was no purist lol.
I got all NGK plugs, and once I put everything back together and get some miles on her I'll let ya'll know what I think. :goofy:
Oh, and when I saw the title " What Spark Plug TYPE you are running on ?", first thought was "Why don't ya start a 'What Oil?' thread for Christs sake??". :fing02:
