Hello,
One thing that might help prevent the sparkplugs from blowing out is to just re-torque
the sparkplugs.

Normally its just one plug that blows out, so if it aint broke don't fix it, is kind of my thought.

The kit you need is a part number 5551 price $256.97 this includes all the tools and 5 inserts
Here is a link to the step by step repair: http://www.timesert.com/Triton-repair.html
These instructions will help you understand the process before you receive your kit.

I always thought kit # 4412E was what we needed?

 

In before the lock ...

We have eight cylinders, right? Why 5 inserts?

 

Most likley because it is meant as a fix not as a preventative measure.

 

I use kit 4412E & 44185 inserts been installing them for years.
