"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."

"These plugs increased my fuel mileage approx.4 mpg and I have not gotten any better performance or gas increase from the other so called copper plugs! And they have never failed me.
I recommend them!
