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!

Pros: feels way better, car smooth

Cons: CEL about to come

Vehicle: Volkswagen Golf

Part number: NGK1675

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.

Pros: car runs great

Cons: varying degrees of tightness

Vehicle: Volkswagen Golf

Mileage: 20000 km

Part number: BKR8EIX

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.

Pros: never let me down

Cons: Champion plugs failed

Vehicle: Suzuki

Mileage: 1500 km

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...

Cons: over fueling, misfire

Vehicle: Volkswagen

Part number: BP6ES

I've been pulling my CR8EIX iridium plugs out to check how they are burning a lot recently. I've been seeing some light ash deposits and high speed glazing and the iridium tips of the plugs are not as hot as I would expect them to be, i.e., they are not *white*.

Cons: light ash deposits, high speed glazing

I put in NGK PFR7S8EG plugs and man the car ran like absolute CRAP when it was cold. It ran fine, even great when it warmed up but it was so bad when cold that it was virtually un-driveable especially under moderate or hard throttle. I ended up putting the old plugs (Bosch platinum/iridium) back in because it was so bad.

Pros: ran fine when warm

Cons: ran like crap cold

Vehicle: Volkswagen Passat
