It's a simple part, but it's one of those upgrades that makes maintenance a lot less painful. Whether your nozzle is worn out, cracked, or you just want to swap springs for tuning purposes, this plug makes the whole process straightforward.
One thing to note: use the original o-ring from your stock plug when fitting this. It gives you the best seal and saves you having to source a replacement.
