e3 Sparkplugs Claim to Save Gas

with 10 comments

Here’s a site that shows what an e3 sparkplug looks like and what it claims to do.  I find information like this interesting.  Once again some company has come along with some gadget that it claims will improve your gas mileage and all for a high cost.  If spark plug design affected mileage that much the manufacturers would put these plugs into the cars when they were built.

Here’s the deal.  The plug sends a spark through the compressed fuel and air mixture, lighting it up.  As long as the mixture burns the plug has done its job.  If the mixture is not lit you will feel the engine miss and lose power.  The spark plug could have any shape, as long as it lights the fuel and does not fall apart, that’s all it has to do.

The only time different spark plugs will affect your mileage is when the old ones are fouled and are no longer lighting up the cylinder.  You will want to put the proper plug into your engine.  This means the plug the engine was designed to use.  Using the wrong sparkplug can damage your engine.  The shape of the ground lead on the plug is not going to change your mileage.  The way you drive affects mileage.  The design of the car affects mileage.  The quality of fuel affects mileage.  The spark does not propel the car forward, burning gas does that.

Gasoline is expensive these days, and the price keeps going up.  If you are worried about low fuel mileage, sell your hummer and buy a nice little four cylinder car.  Spending lots of cash on dubious products that claim to save you money will only get you deluded and burned.

  1. These plugs were designed for a more complete burn in the cylinder to reduce harmful emissions. especially in smaller engines.

  2. The proof is on the Dyno, take a look at and the test they performed on the Dyno, E3 plugs out performed the compitition by a boost of 5 horse power and slight improvement on fuel consumption. Granted the amount of increase in fuel consumption is probably not that compeling a reason to use the plugs but 5 hp when looking for more ponies is a lot for just changing plugs.

  3. I installed these plugs and after about 700 miles started getting a miss at idle and also when accelerating below 1500 RPM. Put back in stock plugs and everything worked fine.

  4. Water Car Run on WATER+Fuel. Hydrogen Save Gas=FREE ENERGY!…

    The whole gas cost thing depend on how much money you earn at your job, those in the higher brackets dont really care if it goes up pennies or dimes, they just fill up & drive away as usual. I dont drive a lot but do have a GMC pickup, being 6\’6\”…

  5. Ive got the E3’s on my car, and as soon as i put them in i noticed a difference. the pickup was better, the gas mileage was a little better (not much) and the top speed increased by a few mph.

    if you want a cheap and easy way to up the hp of your vehicle, drop these in, get a K&N air filter, and you should see a change immediately.

  6. I used to run SplitFires in my Jeep Wrangler until I could get the issue corrected. I didnt always. In the beginning, I ran Autolites. But when the prob surfaced, I said what the hey, and bought a set. Even after I corrected it, I still ran them. They were simply impressive. They outdid the average plugs. These cost about the same as the SF’s. I now have an older Ford F150 and cant get SF’s. Both plugs work on essentially the same principle. They will run more easily in a oilier-than-normal environment (I’m not saying they’ll run on oil). I’ve got to change my plug wires; Think I’ll give these a spin as well and see what they do for me. My expectations will likely be met. Will post back later on, if I can remember to.

  7. E3’3 Suck… A 30 minute show with a few minutes on a dyno only shows how long they work not how well, any plug will give a lill extra out of the box If You still think they are Great get some extras so you dont have to spend every other weekend at the parts store…..”E3 When Quality Don’t Count”

  8. Dont buy these spark plugs. I purchased them about a year ago and my car has been misfiring since. I never thought it would be the plugs because they were new. But I decided to put back my stock plugs and the misfiring stopped instantly. The manufacturer refuses to refund my money.

  9. These are the worst plugs on the market! Please DO NOT waste your money! The warranty stinks! It cost me $200.00 to get my car back to normal. All the warranty covered was a refund on their junky product. I got stuck with the repair bill caused by their plug that blewout the plug boot.

  10. First, to say a plug brand is no good and offer no proof is just your unfounded opinion. No plug is capable of blowing off a boot! In our speed shop we see a lot of people installing these E3s with no problems. We have however fixed problems with E3s not installed properly and that accounted for all the complaints we witnessed. One had not installed the boot correctly and lost full contact. Another where two plugs were loose and caused blow-by and a third was plug wires pulled by the wire and not the boot and pulled out the wire from the clip thereby causing mis-firing.
    The comment that any spark ignites and that’.s all there is, well if that’s true any spark will work and they’re all the same (lets get rid of all those high energy coils, wires and ignitions!).
    Another comment: “if they were any good at saving gas all the manufactures would install them.” Yeah, that’s such a good point, Manufactures always install the best oils, filters, mufflers and tires – somebody tell that to K&N airfilters, electric fan manufactures, exhaust system makers. cold air induction makers and Gale Banks among many others they’re missing the boat.
