90% of NGK's are fake, that doesn't mean you need to buy from them. Even copper plugs will work but not give average or long life.
@nomi01 is selling original NGK's and i can tell they are genuine because i myself have suffered a loss due to purchasing cheap NGK's from a non-authentic seller on facebook although the seller agreed to return it but I still had to reimburse them shipping costs + bear reshipping costs. Anways..
Genuine Plugs can be purchased from Parts Central PK
