Everyone needs to keep in mind that these "rare earth metal" materials like platinum, iridium, etc. are used to prolong the life of the spark plug, NOT because of it's performance. Copper out performs ALL current spark plugs on the market except for silver plugs. Spark plugs have ONE job: to deliver spark to ignite fuel. No matter what marketing techniques or what you heard or were told, none of the other plugs will work as well as copper. The best conductors of electricity are 1) silver, 2) copper, then 3) gold. Now in terms of which plug lasts the longest, then yeah, copper would be a poor choice, but seeing that the job of the spark plug is to conduct electricity and send it to the combustion chamber, then whether it lasts 20k or 40k miles is irrelevant.
You forget that even though the copper is one of the best conductors, it does not matter much in case of spark plugs because of high voltage and relatively low current going through them. In fact, some resistance is integrated in series within the spark plugs to counter the EMI they produce. What matters is the constant gap between the electrodes and the long-term endurance of the iridium material.
ALL spark plugs used copper in the inside, the pointy thing in the tip, in "copper spark plugs" are actually made from nickel alloy. Why people keep spouting this siht?? Stupid but vocal Why dumb people keep spouting this siht??
There’s no question about it. That white hot spark will burn hotter and fire a lot better and burn cleaner and save gas money. The iridium will also last at least 100 miles or longer.
About the concentrated spot on the iridium, it burns hotter because it is a smaller surface area. It'll clean off any build up that may get on it and be cleaner than that copper plug. That's a test you could see for yourself. They just burn hotter. Iridium also has a 700C higher melting point than copper. But, yeah, smaller surface area, same electricity, hotter tip because of that smaller surface area. It'll actually stay cleaner than the copper plug.
@@xinjinping8113 Same amps and volts (aka watts) spread across a larger area vs a smaller area. Which one gets hotter? It's exactly why they're always talking about cooling issues with CPUs getting smaller and smaller (ie 14nm to 5nm). When they both pull 100 watts but one has 3 times the surface area to dissipate the heat.
don't forget that most of these "high performance" engines today make changing spark plugs a b*tch to do... even on subaru boxer engines. So, one reason to go iridium is so you don't have to change them every 50,000 - 100,000 kms. For those 4 cyl motors where the spark plugs can be done in 30 mins or less, then yeah... go copper and replace every 40-50k.
Hello! Denso Cooper are good spark plugs. Just like anything else, parts or components will always going to be replace sooner or later. Thank you for sharing and take well care!
I wonder if only the tip is Iridium otherwise the other contact of the plug will degrade. I also noticed that because they use the iridiums longer, the ceramic shielding breaks off. That's not good cause it can cause engine damage.
Hola Chano. Me gusta tu canal. Lamentablemente la barrera del idioma me hace imposible comprender tu video. En conclusión ¿cuál de esas 2 bujías es mejor y por qué? Gracias por tu tiempo y conocimiento.
FYI Copper is the core material. the tips are still steel. the iridium is only the small tip and the core is.... probably copper. Note the ground bar is probably the same steel material. But the tiny iridium tip does last longer than the other type. Thus the possible 100,000 mile rating. You can't even find the dip stick on new cars..
You doesn’t choose the best one from iridiums my friend . Denso Iridium TT are the best ( double tips) . Also NGK ruthenium ones but they still have ticker central electrodes , which is determining for the amount of breakdown voltage needed . Denso Iridium TT has only 0.4 mm diameter central electrode and NGK ruthenium 0.6 mm . Cooper plugs has 2-2.5 mm diameter central electrodes .
Iridium lasts around 160,000 km the v-power works pretty good but doesn't last that long maybe 50,000 km for me the longer I don't have to change it the better
instead of coper buy the dual PLATINUM, it is stuby like coper plug but hard like titanium plug. Stuby fires evenly all the time where the titanium pin doesn't always have a good single direct path to fire the mixture. Try both to realise that dual platinum is better than tiny iridium.
My 2010 tacoma came with copper and toyota manufacture recommends copper so i believe copper is better choice bcause when i switch to the irradium twin tip i lost more gas mileage.
it all depends on what the driver needs, if he needs one which can extract power or response in a more fuel feed the platinum would have an advantage with its wider range of sparks with all those multiple arcs produced it could burn more fuel faster than what the iridium does, but iridium have the advantage of that single fatter and hotter arcs produces in a center and a far more reliable matterial that could last way way longer
Copper is better. I always only use Copper due to the fact it is very easy for me to get to my spark plugs in my 94 chevy shoutbox, and my 98 GMC Yukon SLT. Both are 5.7ci, and it only takes me 15min to swap the old out with the new.
No nomás el material de la bujía pero también saber la diferencia entre bujía fría y caliente dependiendo de varios factores.en el tipo de automóvil oh carro modificó!
HelloTHEO! Both are good spark plugs. copper are just fine for a daily driver. The reason iridium are good too, is because they last longer and performance wise to us both work the same. Always use what is been recommended by your car manufacturer. Take well care THEO!
You can get better fuel mileage with copper nickle tip plugs but they peak out at around 15k- 20 k-30k for stop and go average drivers ,It depends on hours of usage ,not just miles ..TAXI Cabs maybe 5 to 7 k .. Long distance every day drivers ,it can go up to 50 k + ..
Hello SilverDollarSaloon! Cooper spark plugs are called like that because the material that is used to make the electrodo or the point at where the spark or ark is created. When looking at a spark plug, one end has the recover for the spark plug wire to slide right in to it, the other end is put facing inside the engine and that end has the place where the spark happens. That end in the middle of the spark plug would be surrounded with porcelain and that material in the middle can be rather copper or some other fancier material and that’s why they are call cooper, iridium or platinum. Hope this info can be helpful to you. Take well care SilverDollarSaloon!
IRIDUIM and Platinum kicks Copper Nickle PLATED Tip PLUGS in the ass in mileage but performance and better fuel mileage ,good ol copper nickel tip is the best ..I wish the makers could combine Iridium and Copper- Nickel at the tip ..
