Spark plug Bosch or NGK

NGK BKUR6ET-10, stock number 2397. With every other car I've owned, the first symptom of failing plugs is missing at higher rpms. In the AEG engine, the first symptom is that it gets hard to start. Do you find that too?

I literally JUST did this today to mine. used NGK 3967's (about $4.27 a piece)... And also replaced the spark plug wire for about $30 using NGK 4412.

i run NGK BP6EFS, no issues with them on 2 engines so far

I’ve run NGK platinum and Denso and they both work well.

I use Bosch everytime I can, minus their $90 spark plugs lol

Anyway, I finally made the effort and took the plunge, choosing the offline method of sourcing the NGK. That aside, the first pull on the throttle, I felt the difference. It was, for lack of a better word, 'softer', an easier pull. The change showed up in various other ways. A smoother ride, easier acceleration, an hour or so later, easier gear shifts and the ability to be in lower RPMs and speeds in higher gears.

Avoid the NGK’s Bosch or “Volvo” (also Bosch) plugs are way better than the NGK’s.

I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use

I’ve gotten fake NGK on Amazon before it’s very possible

Also dont use plugs for tuned cars if youre not tuned. Tuned cars run colder plugs. They are not the same dont listen to some of these comments lol
