Dealership says they have to lift the engine or something, can you replace the spark plugs yourself by just removing air cleaner and battery for access ?

Just want to point out if you're DIY change sparkplug, do the plug closest to the driver side at the back, that is the tightest sparkplug area to get to. If you managed to get all the tools to take out that back driver side sparkplug, the rest is easy since there is a lot more room.
1/2 turn after hand tight on sparkplug, you will feel the stop tight after 1/2 way. Don't worry too much, reason 1/2 turn is to crush that ring metal gasket so it seals.
I've done it 2x now on the family's MY18. It's doable without even removing the battery. It got tight the second time around as the motor mounts have collapsed some(hence why I'm replacing them), You'll need to remove the intake pipe/hose on the passenger side and some brackets on the driver's. It is mildly snug in there, so take your time and relax for a bit. The special tools you'll need:
1) 14mm thin walled spark plug socket. I used BMW's version made by Hazet (pt# 83 30 0 495 560, hazet # 4766-2)
2) 3 inch 3/8 wobble extension. I used Wright's version pt# 3410
3) 3/8 drive thin rachet. I use craftsman and a Mac versions for this app.
Go easy on the clips for the ignition coils as the harness is not robust.
It’s a job, but I was able to do it with tools on hand. If you have a spark plug socket, a swivel and a short extension, you should be ok. It is a time consuming, frustrating job, but you will save money, if that’s an issue.
Be warned, it takes a while. I've changed plugs in cars but refused to in the Subaru after researching. Many first-timers take at least 2-3 hours. My mechanic took 1.5 hours on a lift. It can be done if you enjoy a challenge.
