    Forced Induction No-No plug

    8 of 8 people found this helpful

    I run a 2010 Hyundai Genesis Coupe @ 16PSI of boost and these plugs fracture insulators with less than 100 miles on them. I have had fractures, loose electrodes, and separation of the seating gaskets upon removal. So far, I have chunked 5 of these plugs!!! I recommend this plug in all other "naturally aspirated" cars and trucks as I have had much success with them in the past. I have used them in the family 03' Honda Odyssey and increased fuel economy and power with the normal tune-up interval.

    Pros: Fires hard on normal applications. Good MPG, Idle, Start-up, "pre-gapped" application specific.

    Cons: Cheaply manufactured porcelain insulator
