E3 Spark plugs
I just installed E3 spark plugs, had them in for about a week, the engine runs smoother and seems to have more power. I'm not sure if it's because of the E3 or installing any new spark plugs would do the same. Also noticed my gas mileage getting slightly worse, then I topped my oil up. Anybody else tried these? And do you notice anything better.

There's lots of threads on Splitfires, Bosch Plus4's and E3's. They are all just a high priced gimmick. If they worked well the OEM's would install them at the factory. Stock or iridium's are your best bet.
