It all comes down to choosing the right plug for what you need it to do, not just paying attention to the brand name. That's like saying "My Bridgestone tires suck." Well what did you buy for what car? The fuel saver Ecopias to put onto your Corvette? Yeah that'll really suck from a performance point of view vs a nice set of RE11s or S04s. Still Bridgestone... but different model numbers for different applications.
    NGK is the OEM supplier for spark plugs on BMWs, or at least for the NA 6 cylinder. My BMW mechanic says that Bosch is better.

    Both Bosch and NGK are BMW OEM plugs.
