I had never heard of that prior to the Pulstars and I had changed out alot of plugs. Learn something new every day.


Installed the Pulstars just now. I left the rubber in the socket so I could lower the plugs down in there as opposed to dropping them down and hoping they land straight. Once they got started, I switched sockets. I did notice the ceramic area had a larger diameter than the rest of the plugs. Had I used the spark plug socket, I would not have been able to push it far down enough to reach the nut.

Another think I though was odd was the plugs I pulled out. I was under the impression that stock cars used copper Champions. I pulled out the stock plugs and they were NGK V Powers. The original plugs also had pretty decent burn marks around the bottom of the ceramic area.
