This forum is supposed to be a friendly place where people can come and get help or help other or just hang out. Constructive criticism with an explanation would be nice. Not "Your an idiot if you do this or that" Why not tell people what about platinum makes then bad plugs.
If you think platinum plugs are superior, then you clearly do not.
That was constructive thanks....
They don't have the longevity of platinum. We have already said that iridium plugs are great, but typically unnecessary. Where did you get that they don't have consistent spark?
They are superior to copper in longevity, erosion, and corrosion resistance which over time can effect performance. Hence why you have to change copper plugs so often. When they wear down you dont get a consistent spark like you would when they were new.
Great. Then platinum plugs are for you. If you want the best performance, use copper or iridium. If you are lazy and don't want to change your plugs, use platinum. Oh, just make sure you change them if you ever plan on using nitrous.
Guess Im lazy then. Must be why I use the 15k mile Mobil 1 oil too. Platinums are perfectly fine for a daily driven Mustang like mine.
Piston-driven airplane performance is quite different from piston-driven automotive performance. Just FYI. The environments they live in, as well as the requirements of the motor are very different. They are not really analogous.
Since your so knowledgeable about airplane engines, what makes them so different than car engines? Oh wait, Ive been an airplane mechanic for the last 12 years.... I guess I could list them for you.
1) Most of them are air cooled. But Porsche, VW and Harley's all used that to so that isnt really one of them.
2) They use magnetos instead of distributors or computers. They use these because of the altitudes they fly at.
3) They turn a propellor instead of a transmission.
4) Most of them are horizontally opposed engines. Oh wait, Again Porsche, VW and Subaru use them too.
5) Most now a days use mechanical fuel injection. Dont see that on cars much any more.
6) Some use turbo chargers to change the altitude at which the engine is operating at. Its called turbo normalizing. And what it does instead of providing a power boost per say, is to make the engine run as though it was naturally aspirated at sea level at any altitude in the airplanes operating limitations. So the turbo operation is clearly different.
7) Airplane engines run 2 plugs per cylinder and 2 magnetos. They do this for 2 reasons. One is for safety. The other is they get a more complete burning of the fuel.
Thats pretty much it. The principles of how an airplane engine works is EXACTLY the same as a car engine. A 4 stroke engine is a 4 stroke engine.
Look obviously you feel very passionate about platinums being crap. And Im not going to convince you differently. I run platinums and am happy with the results. And you think Im a retard for doing so. Whatever....
