You can change the brand of glowplug any time you want, you just have to re-tune the engine afterwards. Same as if you change any other part of the engine.
That's not true. Not all turbo glow plugs fit in all engines, just try to put a Nova plug in a modern Picco and the engine will have a leak, if you tighten a little bit you'll get a nice head button broken (a $40.00 mistake)
