You’re correct, it’s much tighter in the Pathfinder/Xterra. It’s not horrible and I did the plugs on the Pathfinder without taking the intake manifold off - so stubby sockets and ujoints did the trick. I went from the VQ40 2011 Pathfinder to a 2015 Armada. Based on the experience, I’d pick the Armada every day over the Pathfinder. Fuel efficiency reduced by 2-2.5 mpg in my case for a much larger vehicle. I really really wanted a GX460. But after test driving one and given the silly pricing, I ended up with a 2015 Armada. It’s a great family vehicle - lots of space, the VK56DE is very reliable (but has an appetite for fuel) and is pretty comfy and quiet highway cruiser. It’ll last me a long long time barring unforeseen circumstances.
