Getting ready to do a tune up and new to the 4Runner. While I was doing some parts ordering online I came across these "Spark Plug Tube Seal" on Rockauto.

Also there is an item called a "Spark Plug Boot" what the hell is that?
Are these necessary to purchase when doing a spark plug and plug wire change? I just want to make sure I have all the necessary parts before I start this project. BTW...not that it is any major mechanical work but I searched and didn't find any write-ups concerning changing the above mentioned items. Anyone know if this has been written up yet?
