High quality spark plugs
Seemed to work great. Made the care sound much less rough when idling. Simple enough to install.

Build Quality Looks Good
The media could not be loaded. Overall inspection of spark plugs looks excellent. I don't have a way of verifying if these are legit or not. Packaging material looks authentic also ceramics, threads, contacts, washers and iridium tips looks solid. Please note they are magnified. There is a laser engraved M25S on the ceramic also. With my thorough inspection, I believe these are legit.I cannot rely on tube videos since those 6 point type NGKs.I'm giving it a 4 stars for now to be fair and I will update it after I installed and verify performance and if the misfire on no.4 cylinder goes away. I switched coils 4 and 5 see if the misfire follows on 5 then it's the coil. I have MHD stage 1 plus on my 2016 Z4 3.5is, and the misfire just happened recently. The CEL reset itself after restart. The Bosch plug looks OK. The thread is coated with Anti Sieze compound. I will post an update review soon. Just waiting for the gapping tool. Some recommend 0.22 and others 0.18 for 2 step colder plug. I will gap it at 0.20 to be on the safe side for now.Update:I duplicated the acceleration that caused the misfire on cylinder 4 and no misfire on 4 or 5 cylinder. I decided to gap it at .022 since .020 is too narrow for a colder plug.I could feel the difference in smoothness running at idle.It seems like my power decreases a little bit but it just actually runs much smoother in all RPM ( no redline )than before. I really think that these plugs are genuine and if you added more HP on your N54 engine, switch to these plugs.

Great value, performance improvement
Replaced the plugs in my 2011 BMW 335Xi. The performance and gas mileage has improve. Still satisfied after 3 months of driving and 10,000 miles. I commute on long drives daily and love the response from the new plugs and coils.
