be careful, on my 200 v10 I changed the plugs and a month later the engine spit a plug and scored the cylinder and a rebuilt engine was cheaper than fixing it. So I traded it in for a 2005 diesel. I am told this is a common problem because the threads could be deeper.
Mark
so is there something that can help prevent this??
I am just over the 100,000 mark and I have no idea how old the plugs are!!
I have owned it for 3 years but have put less then 20,000 on it.
