I tried checking the passenger-side rear one, and there's so much hoses and piping that I couldn't even touch the spark plug with my finger. I managed to pull the boot off with great difficulty... I'm thankful I could get the boot all the way on after aborting my plans to check the plugs.

I'm seriously considering returning my spark plug tool I'd just purchased and get someone else to do them.

I use a little experience, a bit more patience and 3/8" drive extensions with the wobble bar style sockets that allow a bit of flexabllity - be careful not to then short POS terminal on battery with extended tools - makes me jump!

Some in here also buy spark plugs that use smaller 5/8" socket not the 13/16" socket requiring BP6ES. The larger sockets get stuck up against catching of mpfi heads at least. I now have a slim line socket that helps. BCP6ES may be the 5/8" socket size plugs.
Also helps to rmove some bits to access. Stubborn PCV hoses come off with a bit of a warm up from either hot motor, hair dryer or heat gun.

Really important to make sure you have clear access as described - these alloy heads are very unforgiving to being x-threaded

oh yeah, warm ngine first and a thread chaser cleaner upperer is also good tool. Use a piece of 10mm ID rubber hose about a foot long (305mm) shove top of plug in and use it to reach down and thread in hole by hnd feel, less chance to cross thread if you are gentle

I'd use a spark plug socket

Umm.. sounds like you need to move some of the stuff in the way and like Jonno mentioned.. use some sort of wobble/flexi knuckle tooling. These's usually plenty of room so there must be something else blocking it??

He might just be used to removing plugs on an old 70's or mid eighties Falcon six ! Like I was when I started with Japanesey car design - had to shift from 1/2" drive everything to 3/8" and finally 1/4" !!
