A guide for first timers showing how to replace spark plugs on a later LS400
Just a note to amend my own experience. Please read:
I discovered/read a Lexus manual on this and there is a step to applying electrolyte grease to the spark plug threads. Next time I will do this. I have amended the guide - some manufacturers specify no grease and views seem to be divided - but if Lexus specify it in their servicing and tech guides then that's what it is.
There was certainly no sign of grease on removing my plugs...Lexus service history to the then 72k Miles.
