Spark plug NGK or AC DELCO

I had 2 spare, new spark plugs and these got rid of the misfires in cyls 2 and 4.

I ***always*** use NGK spark plugs after I tried a set of Champion plugs in my old GT380, and two of them failed after 1,500 miles. NGKs have never let me down in 35+ years of riding.

Just use NGK and put them in dry, never had a problem.

Checked spark plugs. The plug is an NGK BP6ES for those that might want to know. This is #4 plug, other 3 in similar condition. Would seem to indicate over fueling, or misfire condition across all 4 cylinders...

41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.

Most of my guys like to go with NGK plugs

That’s hilarious I just swapped the exact same plugs this morning in my Lotus, cheapies for iridium, what a difference.

The new NGK spark plugs do not need anti-seize per NGK. The anti-seize is already in the metal.

I run RS3 coils with RS7 NGK plugs in my Unitronic Stage 2 GTI. These things really are unnecessary for anything stage 1.

I've been running these plugs for over a year and a half and hate em, I guess when I got them I wanted new fresh plugs for a hot climate but should have taken them out immediately as there was noticeable power loss. I'm looking to go back to stock now as the car really ran much better. This is an unmodded 08 gti.
