    Smooth and quiet.

    I put these in my 13' f-150 5.0. Instantly they were smoother running than the original plugs. There is a noticeable power increase at higher rpm. Everything else is just smoother. I have not notice any difference in fuel economy which is what I was really seeking. I have used E3 plugs in many autos and small engines before and have always been pleased.

    Trailblazer LT 4.2L

    With this product I feel there is more of a low mid to high rpm range improvement. I have been running these plugs for a short time, but what Im experiencing is well worth it, as for longevity the manufacturer is saying a 100,000 miles, we'll see only time will tell.

    Great plugs

    These plugs are fantastic. I run them in a 1984 Pontiac Firebird with a 5.0 carbureted , a 1989 Honda Shadow 1100 cc V-Twin carbureted, a 2011 Harley-Davidson Ulta Glide 103 ci fuel injected, a 2015 Chevy Equinox 2.4 liter fuel injection as well as a couple of small engine equipment. The E3’s have been my go to spark plugs for years. Easy starting, smooth idle, good power. I don’t track fuel mileage so I can’t say if there’s a fuel savings. I purchase the E3’s for reliability and smooth operations. I recommend them to friends.

    A great spark plug

    I’ve used this brand on my ford F53 motor home and got better performance and they added 1-1/2 mpg increase which doesn’t sound like much but to those of us who drive gas powered coaches its a considerable boost. So I finally put them in my tow-vehicle, a 2007 HHR. so far so good.

    Great results

    Makes my truck run great and has more power and performs better. These plugs are the best that i have tried and fit good to specification no gap to set is a plus, should have tried them sooner.

    Worth every penny !!

    Do you want to squeeze every last penny out of your car? Do you like wasting money at the gas pump? Of course you don't. If you want any spark plug that burns 70% of your fuel or more then E3 spark plugs is what you want. Not only have I noticed my fuel mileage increase with E3 spark plugs but the engine runs flawlessly. These spark plugs are worth every single penny.

    Tow power improvement.

    2014 Ford F-150 XL crew cab 5.0 Had the plugs in about two weeks now. I have not seen improvements in fuel mileage. However I have seen a improvement in tow power when pulling my 30’ travel trailer.

    Awesome Spark Plug with excellent results

    E3 Spark Plus is by far the best plug i have used. I purchase them on Ebay in a 4 pack and no one could be the price , not even Amazon.
