Title: E3 SPARK PLUGS, DONT WASTE YOUR MONEY
Review: I AM A 28 YEAR ASE MECHANIC. I INSTALLED E3 SPARK PLUGS IN MY TOYOTA TACOMA V6. AFTER 1 MONTH OF REGULAR DAILY DRIVING, KEEPING TRACK OF MILES DRIVEN AND GASOLINE USAGE, AND SENSIBLE DRIVING IN A VERY WELL MAINTAINED VEHICLE I DID NOT SEE ANY FUEL MILEAGE INCREASE OR HORSEPOWER GAIN. IF E3 SPARK PLUGS ARE SO GREAT,,, THEN WHY ARE THE MANUFACTURERS NOT INSTALLING THEM.
Is the review positive or negative?
