I replaced my plugs 60K miles ago . I used the Rotorcraft SP515 and put nickel never seize on the threads and electrode body tube. Is it going to be as hard as the first time to get those plugs out . I had three of them break off the first time. Thanks Glenn

 

They should come right out. In the future, no antisieze on the threads. They are non stick.

 

No antiseize on the threads but DEFINITELY put it on the tube.

Before you change them, run Techron through a few tanks of gas and drive it hard to burn the carbon off.

 

Don't want to be a total pessimist, but from another owner of the same engine, I would say have a Lisle tool available before beginning.


Let us know how that antiseize worked out for you.
