rsg3,

Are you a Santa Fe owner?

Have you asked your Hyundai dealership if using any plug manufactured by anyone else besides Champion or NGK would void your warranty?.....well, I have and they said if I installed Bosch spark plugs in my Santa Fe it would void my warranty.

You think Bosch Platinum +4 plugs are waste of money? Hell, have you priced NGK spark plugs? I have and they cost twice as much. Splitfire is about the same price as the +4.

Copper plugs are the best? What type of core do you think the Platinum tip plugs have?......copper.

Do you own a Santa Fe V6 and if so have you removed the surge tank to install plugs?.......hmmm.
GO CHIEFS!
