I run NGK Rutheniums now and they've been excellent handling 30psi of boost with zero blowout even at wider than the .024" gaps that most tuners recommend. Oh and theyre MUCH cheaper at $8/ea vs $40/ea for the NGK race plugs.

Pros: excellent boost handling, zero blowout, much cheaper

Learned 40 years ago to use NGK. Installed brand new Autolite plugs in my girlfriends Grand Prix and it ran like crap. Went to a speed shop and they sold me a set of NGK. Ran perfectly. Have only bought NGK or Denso since.

Pros: ran perfectly

Cons: ran like crap

I replaced the OEM plugs with NGK, they lasted about 15,000 miles. Burger Tuning told me that 15k is about all you'll get out of NGKs in these cars.

Cons: short lifespan (15k miles)

Vehicle: Kia

Mileage: 15000 km

Additionally I would endorse the use of a Champion or NGK plug. The LG/Torch/random Chinese plugs are a crap shoot. I see tons of failures on them as well.

Cons: tons of failures
