NGK all day, compared to all others they’re just made better, I bought Bosch platinum for a VW and the OE came out were NGK, after 50k they were still visually a better manufactured plug. Example- the plating on the Bosch threads was rougher.

Pros: better manufactured plug

Cons: rougher plating

Vehicle: Volkswagen

Mileage: 50000 km

Over the last 16 years with my 8 gas engine VWs and Audis, the OEM or OEM equivalent (Bosch or NGK) at stock gap (unless chipped) have performed better and more consistent than any other I've tried.

Pros: better, more consistent

I’m 90% sure my EGTs came with Bosch plugs, switch to NGK that are 2 steps colder for my tune haven’t had any issues with them for about 25k miles

Pros: no issues for 25k miles

Mileage: 25000 km

NGK and Bosch are the same ones as the Genuine BMW ones. The latter are just rebranded and marked up.
