Spark plug NGK or Champion

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.

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.

The car started to misfire at boost so I swapped plugs to NGK PFR6H-10 and everything is good now.

Don't use Bosch sparksticks.

I use iridium’s NGK haven’t had any issues.

I used champion spark plugs.. no problems here

Just replaced my previously purchased NGK Iridium from Rockauto.com After 100k miles the looked like I put them in yesterday.

I'm running NGK Iridium NGK LTR71X-II 1 step colder but I am tuned. Been running these sparkplugs since the car had 5000 km. I have 45000 km now in 8 years and a half and I have changed 3 sets as it is recommended to change them a bit sooner than 30000 km on a tuned car.

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
