Hi folks, I decided to replace my glow plugs as a preventative maintenance on our 2015 GL350 with 90k miles. Original plugs. Figured replace them now while they're still all working and still easy to remove. I'm using NGK 92340 as the replacement parts.

Plugs 1-5 were easy, no drama there. Plug #6 looks impossible. It's the rear-most one, driver's side. The engine hoist point and the plastic wiring harness bridge are blocking access. What's the secret to reaching this one??

Any tips are appreciated!
