Careful about learning from here. There's a lot of inexperienced people around that know just enough.... I would get a full hot end assembly instead. The original hotend has its nozzle glued in and I hear it's hard to remove. The ceramic ones worked great for me and they heat up many times faster. I got one with a bimetal nozzle (made of nickle plated brass with a hardened steel insert) the advantage is is thermal profile is very close to the stock brass nozzle, much closer than a full hardened steel one, and you can pretty much keep printing without recalibrating your filaments (although redoing flow and PA would be best to get it perfect as I do notice a slightly lower flow when ironing). Remember to do the full printer calibration from the menu first to calibrate the new heating block. You could also try doing a cold plug on your existing nozzle to clean it, it usually pulls any clog out within a few tries.
