"I guess it depends on which vehicle you use these in, but my experience has been disappointing to say the least. I own a 2009 BMW X5 3.0 xdrive with 60k miles and installed these plugs August 2, 2014. the car calls for a Bosch or NGK double platinum. Against my better judgement I went with the E3s. My mileage went down to 17.7 mpg from 20 and there was hesitation when accelerating. I have pictures showing my 60,000 mile Bosch compared to the 2,500 mile E3. The E3 had an extreme amount of carbon deposits while the OEM Bosch plugs had normal wear."
