Did mine myself,I had the socket, same one I use on my BMWs. Not really anything special just the correct size for the opening.

The heat shields need to be moved out of the way on one side, but otherwise very straight forward process.

The M5 was a different story as a lot of stuff has to be removed to get access.

Similar story for the Avalon.

But the Boxster was easy to access based on the location of the plugs. Just a few bolts for the heat shield. I don't think the 6 cylinder is that much different than the 4.

after borrowing my friends a few times I finally ordered my own. Just put it in my stocking. I also bought replacement parts for my QuickJack and a few new Waze Cams so I just wrapped them LOL.

I was surprised to read that the newer engine now needs a even smaller socket. At some point they are going to be kicking themselves as the shops have to keep replacing sockets when the break. How thin walled can you go???

Yes I know, usually not an issue, I believe someone posted here or on F90 site with issue getting a plug out. Guano Happens.
