Reviews of OEM MINI spark plug

We have a 2014 (F56) 2 door, Cooper S, manual. I bought it for my kid pre-pandemic and we've put about 50k km's on it since buying it. Zero issues. We do our own simple maintenance, oil changes, spark plugs, brakes etc and it's no different than any other car really in that respect.

Apart from the usual maintenance when you first get the car, oil change , all filter changes, spark plugs (get iridium 4point) they are around £50-£60 for the 4. They come with them from the factory as well, I just got them myself as mini wanted over £100 for them.
