    It happens all the time and I fail to select the best lineup of brands to test. So, I would greatly appreciate your help. I periodically ask for a vote on which brands to test. The “vote” notification only goes out to those who have both a) subscribed and b) selected the “bell”.

    By the way, the testing is having a positive impact. In addition to helping viewers select the best products for their needs, product manufacturers are watching these videos. Several manufacturers have informed me that they are working to make their products even better. Thank you very much for supporting the channel by watching the commercials and through Patreon support., and I’m looking forward to many more product test reviews in the future. Best regards, Todd

    I would encourage you to retry this same test but using these plugs in a two stroke. I immediately notice a really big difference in performance when I run E3's in my Banshee and my CR500 and KX 500. I mean the difference is a huge noticeable difference. PS. I love your videos. Keep up the great work.

    My guess is that if a spark plug makes any difference in fuel economy it has to do with compression. For good or bad, if a spark plug takes up more space inside the combustion chamber the pressure increases and that in it self may under that specific load may improve efficiency , BUT it does so by reducing the margin up against knock. If the engine were more optimized in A/F ratio and loaded harder the spark plug with better fuel economy might be the one burning your piston or blowing your head gasket. More pressure gives hotter combustion and gives more NOx emissions.

    I have used the E3 spark plugs in all my small engines for many years. I do think the E3 plugs give very reliable starting, especially in cold weather. I have never had to replace a E3 spark plug because of poor performance or failure. E3 spark plugs have worked well for me so I tend to stay with what works based on my experience. I enjoy your testing and think you do very fair tests which give each brand tested a equal chance to perform. I have altered a couple purchase decisions when considering in your test results. However this test will not change my use of the E3 plugs as they meet my needs very well. Keep up the good work, I really enjoy your videos.

    The new E-3 kept missing in my 2006 F-150 5.4l , so I went back to OEM plug and no more misses in the engine.

    Iridium spark plugs... recommend 100,000 miles intervals between plug changes. iridium is used on the electrode & ground strap to resist corrosion & fuel deposits. Iridium is an extremely scarce metal hence their high costMy Experience Everytime I change spark plugs there is A Noticeable Improvement in throttle response, acceleration, overall performance & fuel mileage.I change my plugs once a year regardless of mileage.Note: there's an improvement just cleaning the spark plugs

    My atv (2004 yamaha grizzly 660) never liked to start in the winter .... after about 10 years of that , I switched to E3 just to try and that solved the hard start ....... simple plug change and my grizzly now starts in sub freezing conditions. .... that alone makes them worth it for me

    E3's are GREAT plugs in an '03 3.5 ltr Diamante V6 and they last well. They are definitely better than NGK iridiums that I used to use in the same engine. Now I have bought a set of Pulstars and will try them out and see if there is an even further improvement over the E3's . .

    If you can add a timing wheel in the video with the high speed camera it would add some data.

    E3 is made in China, which I'm not crazy about. The gas mileage test is important, but I wish I can see dyno results as well

    Excellent!!!Feedback: E3 plugs... had a couple fail in 2 stroke engines-chainsaws specifically. Electrode broke @ body and caught between exhaust port and piston. $450 later 😑I steer away from them for this reason. I would like to know they have improved.

    I have used E3 spark plugs in my chainsaw. They seem to be reliable but I had no way of measuring fuel efficiency when working with it.

    In my 02 chevy trailblazer 6cyl (hemo style ) the E3 fouled out in less than 500 miles. Only plug that lasted was the iridium. Never tried pulstar. But from the plugs I did try were ngk,champion ,e4. Then the iridium which I will NEVER use anything else. Great job on all your videos. I would like to see one on tires. A site called " sweet project cars " claims no tire wear when treating tires with a conditioner.(he used a special kind see his video for the info) and possibly test against similar products ! This would be a GREAT GREAT INFORMATIVE VIDEO TO DO as it could possibly save millions of people tire cost.

    I have built a performance test plant for railroad diesel engines. There are two optical sensors in the middle of the glass cylinder to measure its fuel cost. Fill the cylinder to full and perform preliminary operation up to the first sensor. Continue as it is, and record the time when it became the second sensor and the output integration during that time. A small change will affect the output. It was measured accurately with the output rotation speed and a rod scale type torque meter. The relationship between operating time and output is also important. from Japan.

    I had stock Toyota twin electrode spark plugs then replaced them with E3. I noticed more torque, it seemed engine ran smoother on the highway.

    PF, Why can't aviation spark plugs be used in car and non diesel truck engines? Which of the 2 kinds of engine sparkplugs is more reliable and efficient?

    I just stick to the NGK iridium spark plugs as that's what comes in my car from the factory and work best. I don't like any of those fancy plugs. Thanks for the review.

    It would be nice before measuring the fuel efficiency to make sure that all the plugs have the same spark gap (adjust them using filler gauge) Or, maybe, it is only important for injector motorcycle engines.

  • NeutronicalGaming

    I'm sure you can understand more powerful spark = faster burn and faster burn = more efficiency you have the whole cylinder of fuel ignited and creating pressure at one time rather than waiting till half way through the stroke for it to peak, it can be a big deal, but these days spark-plugs are kind-of a known quantity so the gains of moving to something more performance oriented are minimal, still it's backed by good science theory so i see no reason why they couldn't improve engine efficiency, if you really wanted to push to the extreme making something that can cast a giant spark across the whole cylinder head diameter would be the thing to try, combustion would start in a huge ribbon and spread cylinder wide in nanoseconds, it might even generate significantly more torque because pressure would peak earlier and start the piston moving with much more force in a smaller relative area, as the piston hasn't had a chance to move away yet, the pressure gain should be significant.

    I'd be scared to use anything other than what's recommended in fear of blowing my engine or running weird.

    If there not a resister spark plug . You will take your coil out in any small engine . I can flat out prove it .

    The difference was so minimal that even a drop or 2 variation would make another brand win. I figured there might be 3 or 4 % difference, but I wouldn't change brands for such a small difference. I'm going to stick with iridium, because they last forever.
