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...
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.
So the BKR7EIXs are in and gapped to .028. Man what a difference. Everything is so much smoother and the engine doesn't feel strung out anymore.
Replace the spark plug with a genuine NGK plug.
I always get the oem brand because that works the best for your car. I get NKGs for my vw beetle
Iridium, tried and proven. Ruthenium looks like is an experiment by Ngk, I would give ti some time before these plugs prove themselves reliable before buying.
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.
