Spark plug Bosch or OEM BMW

I am running LiquiMoly Molygen at the moment, use LiquiMoly Engine Flush and Direct Injection Cleaner when chaining oil, put in new Bosch plugs and coil packs about 9 months ago.

I used Bosch iridium spark plugs in my 2018, no issues

I've had my Bosch platinum spark plugs in for 120k+ kilometers and they still run as good as they did the day I installed them, back in 2011.

the original spark plugs died (delphi) so i changed them for Bosch ones

We used to put Bosch W7DTC spark plugs in them. No gapping required, smoother idle, and they last 60k miles, maybe more.

Also, some engines get particular about plugs. Bosch has a bad rep for the 3400 engine in my Grand Am, while NGK and AC Delco(I've got NGK Iridium IXs in there now) are fine.

Took original plugs out at 50K miles. Not awful but electrode partially rounded with increased gaps. Stock plugs are Bosch and apparently copper core, so I replaced with same. Recommended gap is 0.043'' Added anti-sieze to threads for easier removal next time.

Don't use Bosch on 90s Toyotas.

I think I just went back and got the Bosch. Couldn’t return either because I jacked up the nips trying to tweak them off ????

Champion is OEM and what we suggest at work, but NGK has never failed us with any application. Bosch is generally terrible and we only use them if it’s a very specific application.
