Types of Spark plugs | Which is Best?

[@TheShornak]

I worked in a Honda dealer in the service department in the early to mid 90's. At that time those multi electrode spark plugs were becoming popular. I remember a customer coming in with his brand new civic. This was a 93 I believe. He complained of a rough idle and wanted it fixed under warranty. But what the technician found was the customer had replaced the spark plugs to those dual electrode plugs. All we did was put the factory plug back in sure enough the engine ran smooth as it should.

[@arturama8581]

That's with most 'after market' stuff. The manufacturer doesn't put wrong parts in your car. Different (colored) spark plug wiring, other size tires, spoilers; it may look nice, but it usually doesn't enhance the ride. Unless you do things with your car that it wasn't really intended for. For the general owner; keep it standard.

[@chrissmith2114]

As the video points out, the bigger the gap in the plug, the more voltage is needed to jump it... This means that leaving the spark plugs in too long can cause the electrical insulation in the coil to break down and cause the coil to fail. When the power to the 'primary coil' is interrupted the magnetic energy in the iron core collapses and is transferred to the 'secondary coil' and the voltage in the secondary coil will keep rising until it is relieved by the spark happening, if the gap is too large the voltage can reach extreme levels. The use of Iridium and platinum is to massively reduce the 'spark erosion' that causes gap wear, so this allows plug gap to stay in specification for a lot longer. Many coil failures are caused by the plug gap being allowed to get too large

[@markrainford1219]

I have had NGK iridium plugs in my 2002 Rav4 and have had zero problems over the last 7 years whatsoever! If you have a new car the NGK iridium are highly recommended as these spark plugs will last at least 15 ~ 20 years! When I removed the NGK plugs after 7 years the plugs were a little brown in colour but looked almost close to new!

Modern cars are complex piece of machinery !? How ? Have you even looked at some of the more complex military vehicles? Car computers have little to do, so usually, the auto makers use 3rd or 4 th tier computers for their applications, never leading edge, that will be a waste of computer power, save them for other more demanding uses. Gradually, since 3 decades ago, engineers started assigning more tasks to the computer, such as alternator regulating, cruise control, radar collision, monitoring etc. How the military handle the complexity, they don't, not when you getting shot at. If there is a significant problem with a tank engine or airplane hydraulics, they crane the whole engine out and replace it with another one, called power pack. Or hydraulic pump, The whole power pack take just an hour to change. Then the old one get sent to the rear with the $million dollar equipment and technician to fix.

Thanks- in spite of being a mechanical engineer with 60 years of building engines; I learned a few things from your video. Note that pre-WW 2 piston aircraft engines used multiple spark plug grounds for their magneto-fired engines apparently for more reliability, so this is not quite a new innovation. Racers also found it's also close to impossible to re-gap such plugs without damaging or breaking the center electrode.

[@CedroCron]

The information about Hot and Cold plugs were good... I do find that colder plugs in a hotter plug specified engine such as those that have fuel/air mixtures on the leaner side such as Chrysler Lean Burn tuning, seem to give a smoother running engine and don't foul so long as you don't go too much colder. Ford also has a new sparkplug in the later Ecoboost engines that have a copper crush washer and when tightened to the specified torque, they will all be properly indexed the same way due to the threads in the cylinder head and threads on the plugs being in certain alignments causing the plug to always align in a specified manner to encourage a more complete burn.

[@kelvinnwosa6885]

Has anyone noticed that modern equipment have become less simpler but more complex. There are creating an ecosystem where you keep needing their services and keep paying them rather than doing it yourself. The concept is profit driven. Once you make a simple machine very complex the more money you can make from sales and repairs.

[@hagerty1952]

That's a very cynical take on the situation. The main thing driving complexity is government regulations. Politicians have absolutely no idea how things are done when developing a machine as complex as a car, so they blithely make requirements and mandates which drives (no pun intended) this complexity. The fact that it's bad for the consumer is left as a problem for later politicians.

[@stinkycheese804]

Actually in the case of engines, it is about meeting fuel economy numbers due to both government mandates, and consumer demand, for those majorities of customers who only understand a bigger number without the detractions to get there, or it's save money now, pay later since new car buyers tend to be better off financially and can just sell or trade in the vehicle before they have to deal with more expensive repairs.

In many published dynamometer runs since the early 2000’s both car and bike magazines have shown that multiple ground-electrode plugs cause engines to lose 2-3 h.p. at the medium to high rev ranges.

Not always. Sometimes manufacturers make mistakes. I have a c4 Corvette with the lt1 engine. Factory spark plugs were garbage. They were intended to last 50k miles; however, the platinum pucks are known to just fall right off. I changed the factory plugs with 40k miles on them and the majority of those pucks were gone, leaving a plug gap 0.015" wider than those with the puck still present, and way out of factory spec. The plugs were also hotter plugs than necessary presumably for emissions. I moved to a different plug 1 step colder than factory with pucks that won't just fall off at random, and it ran so much better.

This video was not written by an engineer. Most of the terminology was wrong, the different metals are only chosen because of their melting point, hardness and heat transferring properties. Electric conductivity has nothing to do with it. Infact some parasitic resistance is desired because it reduces the current trough the ark and this results in a longer, more stable spark, in less radio interference and less strain on the coil pack and it's electronics. Resistor spark plugs are very common these days, but the parasitic resistance can also be in the cables or in the plug connector. 5 Kohms is the most common value.

Once upon a time, pre mandated unleaded fuel, only Amaco premium gas was lead free with an octane rating of over 100. With leaded gas, 10,000 miles was about the limit before needing replacement...along with the points and setting of point "dwell" and ignition timing. Spark plugs are cheaper now than they ever have been, not even counting inflation. Iridium plugs are da bomb. I've got over 200K on a set and they are just fine.

One very expensive repair is when an engine invests water and hydro-locks, bending connection rods and ruining the motor. Adding a pressure-release valve would be difficult to retrofit, and probably require a redesign of the cylinder head, but what if the spark-plug was designed to be this pressure release valve? Then you could retro-fit any gas-engine. Boat motors are the obvious application, but I feel the military would be very interested in accelerating the recovery time of a submerged vehicle. Off-road vehicles, and motorcycles would benefit. As this video mentions, replacing the spark plugs is one of the last things a casual owner can replace. I would think the insulator would provide a route to making this idea work.

If chances added up to establish more than one ionization pathways simultaneously, there will be benefit in multiple electrode plug. The reality is when the first one ionization path is completed, this path will draw current and the ignition coil high voltage output will drop very quickly so that the potential second path will not get enough voltage to develop further.

I have a 2000 Volkswagen Passat with a 1.8 t engine. I have run Bosch plus fours in this since I have owned it. It doesn't run well on anything else!

If you ever go to start your car and it cranks but kinda struggles then starts it’s usually worn spark plugs. Also it can effect fuel have you ever gone to the gas station filled up and then after a few days your almost at half a tank empty. All signs it’s time to change the spark plugs.
