E3 Spark Plugs E3.56 Automotive, Truck, Van and SUV OEM Replacement Spark Plug

I first tried these in a 2002 ford ranger 4.0, I went from 14-15 mpg to 16-18 in the ball park of a 2% increase, and better starting and a power increase.

Today I put a set in my 2007 FJ Cruiser 4.0, again and probably even more noticable power, and I can tell you when I filled up yesterday, I got 15.1 mpg, After I put the plugs in and did my running, and refueled, I hit 18.5 mpg. So yes, I feel these plugs are worth the money, I definitly recommend E3!

I put these in a 2000 Dodge Durango 4.7L. The difference was amazing. Better gas milage and smoother running. Great Product!!!!

I wasn't sure that all the hype over these plugs would prove true... but it DID! Like others, I just had to try em out. I must say that the item wasn't the best finished product I'd ever seen, but performance was noticeably improved. Starting improved (as with all new plug installations), idle was smoother, acceleration was smoother and torque stronger. I also noticed my rig had better and smoother punch in the "over-rev" portion of the tachometer. I'd say these new plugs are well worth the effort. My 4cyl Toyota Tacoma doesn't make neck-snapping power, but it responded very well to what I believe is improved ignition provided by these plugs. I like good plugs, and have used Splitfire Triple Platinum, Denso Platinum, NGK Iridium, and others... I threw out a set of Iridiums when I installed these E3's. I'm not going back to any of the others. I'm an E3 man now. Give 'em a try, I think they'll prove to be the go-to for that little extra boost of reliability and power. Overall, I'm very pleased.
