Guys and Gals,I removed my Bosch platinum +4 plugs today for 3 reasons.1. I did not use anti seize when I first put them in.2. Concern about possible heat range/knock retard issues3. Concern over broken electrodes.Here is what I found out.About the anti seize. Use it PERIOD! I was worried about aluminum head thread failure and went through some tense moments getting four of the six plugs out. The other two were actually loose.Turning wrenches for 25 years gives one a feel for when threads are getting ready to fail and I got that nervous feeling on four of the plugs I removed. All six ended up coming out alright but you can bet that the ones going in got anti seize on the threads.On the heat range concern I really have no way of telling and the same concern may apply to the new Bosch Platinum +2s I put in. Regarding the possibility of a broken electrode. I intentionally bought the +2s because someone wrote about how much larger and stronger those electrodes were. He lied. They are precisely the same electrodes just two fewer.Pics hereOff to the track tomorrow up at Cecil County to enjoy a 30 MPH tailwind!
