    Great experience, My Fenton glass Arrived in one Piece...from west coast to east coast...The wrapping job was well done by seller. 😊 & They're just beautiful... My only negative is GA. UPS left the box Balancing on the RAILING of my porch Instead of placing it on the front porch deck...Easily could have fallen off railing and got broke! My guess is just lazy Delivery Person to walk five more feet to front door. Seller excellent job! Georgia UPS DO BETTER!

    Noticeable difference immediately!

    Recently notice a drop in performance on a 2012 Toyota Tacoma Pre Runner 2.7L, the engine had 237000+ miles so I bought some NGK Iridiums to replace the old plugs only to find that performance dropped off even more, MPG down and poor power on hills. Did a little research and found the E3.68 and swapped out plugs. Almost an immediate difference in how it ran and already getting that early on 23-24 MPG on the highway with it fully loaded in camping and prospecting gear. MPG had dropped to 19 mpg on the highway with the other plugs and now it's like I'm driving a new vehicle again.

    Great price for these spark plugs. They cost less than the OE, which is nice when you have to buy 16 of them for your hemi! I now have E3 in all of my vehicles including my lawnmower. Installation can be very easy, or extremely difficult depending on the vehicle they’re going in. Really woke it up.

    Best Spark Plugs

    e3 Spark Plugs are the real deal. I have a Spark Plug Tester and from my vantage point, the e3 Plugs do produce a considerably larger spark than do conventional spark plugs. Moreover, my Tacoma V6 tends to be more responsive, cruises on the freeway effortlessly and gets better fuel mileage by 2-3 MPG…. I highly recommend e3 plugs!!

    Excellent Spark Plugs.

    I read have used these spark plugs in several of my cars and I always feel that the response time (engine acceleration) is always faster. Not necessarily more power as it is faster response to acceleration request. Always happy with them.
