Most people underestimate those little buggers importance. With a proper material / temperature/ brand of spark plug you can re-gain up to 15% of your cars fuel efficency. On sports car a properly temperatured spark plug can increase horse power by 5 hp (test done on 2006 Mustang Gt).
Most common mistake:
Using wrong meterial spark plug (Most car after 1998 uses Platium spark plug or Iridium Toyota and BMW)
Using a regular cooper plug in a car that regularly uses Iridium cause mis-fire and reduce engine life. Not only that is also will result in bad fuel efficientcy. ) Find out what your car takes in your cars user manual.
Myth about American car can’t use NGK plugs. (In fact in 2004, 70% of American build vehicles uses NGK spark plug)
Changing spark plug only if one of the cylinders stop firing. Spark plug should be check every second oil change, and be replace atless every 75000 KM (although most manufactures claim their spark plug is good for 100000 Km)
Easy power and fuel efficency
Use colder plugs (Spark plugs are defined by not only material of ignitor. by also by heat range)
Colder plugs lets your engine run leaner. Cars equip with Valve-Timing Control tend to run rich (too much fuel too little air) which is just wasting gasoline.
Use Iridium plugs (Iridiums are much tougher material and gerneral fast and accurate sparks) Iridium also have longer “Spark life Spam” which makes it last nearly twice as long as copper plugs. [Irdium is the only plug that should be in your engine more than 75000km]
2wild, your posts are painful to read - misspellings and grammatical mistakes abound. Please, as a sign of basic respect for the reader, do a quick proofread of your post before you hit “submit”. If you don’t want to take the time to write a proper post, why should we take the time to read it?
2wild4canucks, I appreciate that you’re trying to share useful information. Maoman makes a fair point, though. I’m usually more tolerant than him of non-standard writing styles, but this post is just plain hard to understand. Presumably it’s aimed at people who don’t know much about spark plugs, so here are some points to think about:
[ul]How are readers going to figure out that by “cooper”, you mean copper?
Why not make explicit the connection between plugs of a lower heat range (colder plugs) and valve-timing control? (Should that be variable valve-timing control?) You explain the term “rich”, but you don’t say that it’s the opposite of “lean”.
What do you mean in your final point: “Use iridium plugs”? Can all cars take those plugs, or only what you call “car after 1998”? If I read the user manual and it doesn’t mention iridium plugs, can I still use them?[/ul]
My suggestion is to try posting this again, with correct spelling, reasonable grammar, and a better understanding of your audience. I’m locking the thread and changing the title. I’ll leave it in the Cars and Motorcycles forum for now, though, so you can find it easily.
