Spark plug NGK or OEM Volkswagen

Car is very picky about spark plugs because it uses the spark plugs as knock sensors, I used basic NGK copper plugs and replaced every 10k. Very easy to do.

Just changed my spark plugs.. went from 031/032 factory NGK1675 gap down to 027/028 gap (based on the feeler leaf gauge). i am here to state beyond shadow of a doubt that 027/028 gap feels way better. The car is smooth.. so smooth in fact that it makes me feel like the CEL is about to come on. In 7 years of ownership, I never felt it as smooth as it feels now. When idling I almost feel as its off.. also at speed!

Got new NGK BKR8EIX pugs today and gapped them to 0.024". Originally, 0.030" according to my gauge. Very surprised when I removed the old plugs as they were all at varying degrees of tightness even though they were originally torqued to 25NM. Car runs great with the new plugs. No complaints so far.

I installed 2 remaining NGK that I had into cylinders 2, 4. Vehicle is running like new right now.

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...

I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

I have replaced many brand new NGK's in newer chryslers after the customer gets them from a parts store. NGK's can and will cause ignition coil secondary circuit codes. Also, on hemi's they will set asd control circuit codes and cause the car to stall.
