So I looked at several so called high performance plugs and thought about a couple brands like the plasma producing plugs that were $12.00 + per plug or more, but the reviews were mixed and unreliable, so I kept searching, I decided on the E3.74 plugs for my prized Camaro, she's a 2014 model and has 20,000 miles on her, before I made any modifications to her she got an average mileage of 18.9 mpg around town and 27.4 mpg or better on the highway when she was completely stock, I recently started upgrading her for performance and looks because she's already pretty but I wanted to make her even better looking and better running. The first think I installed was a K&N Typhoon Performance Air Intake system, I also installed heat shielding in the AirBox to make it into a cold air intake and also added an air scoop, I immediately noticed horsepower and fuel mileage gains, after the air intake I was getting 19.8 city and 28 highway, now after installing the E3.74 plugs mileage is up to 22.4 in town and 31 on the highway, I expect it'll go up a little more over the next couple weeks when they settle in, so far just an air intake and spark plugs made a big difference in power and gas mileage so I can't wait to see how she'll be when I add headers and performance exhaust and a light tune and throttle management system, I am very happy with these plugs and so far the preliminary numbers are promising and I have high hopes for these plugs, and it's nice to know they have a 5 year 100,000 mile warranty which is great for spark plugs? I haven't really heard too many bad things about these plugs except maybe some vehicles were getting an error on their vehicle from pre igniting the fuel which is bad, but it does show that they work really good if they are igniting the fuel faster then the stock plugs, the problem is that the E3 plugs ignite the fuel so fast that the ECM thinks the plugs are malfunctioning So far I am really impressed with these plugs, I had heard of these and similar plugs before that had the larger conductors and electrode and it makes sense that they would provide increased spark because of more surface area, and more spark equates to better air fuel ignition and burn for cleaner emissions and better fuel economy so just the way they are built would hint they are superior plugs compared to standard plugs but the proof is in the numbers, besides the improved fuel mileage I can definitely feel a difference in the throttle response, she just feels peppier, stronger, and the engine purrs with these plugs, I haven't ran it for 1/4 mile and 0/60 times yet, but I can feel the difference when I press the gas pedal and she accelerates faster and smoother and she really seems to like these new plugs, I'll keep a good log of mileage and performance and the difference these and other upgrades make on my Camaro.... One thing I need to mention is my Camaro has the 3.6 liter V6 engine and a lot of people talk crap abut the smaller engine in a Camaro, because V6 doesn't scream muscle car like the big V8's do, but those people are snobs and don't realize that a 6 cylinder car that has 217 HP stock for the 2012 LS series is a lot of ponies for a V6, HOWEVER the 2014 LS2 V6 (my Camaro) has 323 HP ponies in the base package, and then if you add on a couple modifications you'll be able to get an easy 400 HP out of it, if you go even further and invest in a supercharger you'll bolt on another 150HP on top of that, and 500 to 550 horsepower is respectable for any V8 engine so to be able to get 500 and 550 horsepower and more on a 3.6 liter 6 cylinder engine is a massive amount of horsepower, so starting with E3 plugs and a good air intake system are only the beginning and will get your V6 or any other engine well on its way to blowing the doors of any one who challenges your secret weapon... I was going to upgrade the plug wires with performance wires too but, well the V6 doesn't use spark plug wires, oh well on to the next upgrade or MOD on the list, if you want to really give your cars engine a really good upgrade that's not too expensive then these plugs are a great start because for around $40.00 to $50.00 you can give your engine a heck of an upgrade, I mean think of it, what other upgrade can you give your cars engine for $50.00 or less that will do as much for it as these plugs will do? I can't think of any off hand that are this cheap and easy to install that increases fuel mileage, gives it more pep, makes it run smoother and accelerate faster all while saving gas and reducing the amount of pollution your pouring out of your exhaust pipes? If your on the fence about these then do some research and see for yourself, there are lots of videos and research and information on these plugs out there. One last thing of note, plugs like NGK and other so called performance plugs use platinum or iridium as a medium for conductivity and are a big selling point, but the truth is that those metals are less conductive then say copper (E3 uses copper) or the best conductors of electricity are gold and silver but I don't know of any plugs that use silver or gold so iridium and platinum are the metals with the lowest level of conductivity where copper and silver being the best, the reason these manufacturers use iridium and platinum are because they are more durable, they will last longer but you loose performance with plugs using platinum and iridium, so with E3 using copper you know they will conduct electricity to produce a more efficient and stronger spark pulse, try them and you'll love them, I plan on replacing all my vehicles plugs with these plugs on payday because they all deserve to have only the best parts and for the price. I am happy to pay t for these plugs BC ## Frequently Bought Together - E3 Spark Plugs E3.74 Durable, High-Performance, and Versatile Premium Auto Spark Plug with Patented DiamondFire Technology, Pack of 1 - BJSIA 16mm(5/8") Swivel Magnetic Spark Plug Socket Set, 3/8 Inch Drive Thin Wall Socket, 12-Point Design Compatible with Most Cars --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/254844581-e3-spark-plugs-e3-74-durable-high-performance-and-versatile](https://www.desertcart.at/products/254844581-e3-spark-plugs-e3-74-durable-high-performance-and-versatile) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-05*
