i m replacing the spark plugs on my 96 tegra stock engine non-vtech. someone told me on this forum that i should only use copper. does anyone kno if this is tru cuz i always thought that platinum were better.

 

Good thing a phone company didn't make your engine. I've always been told only difference is platinum is more money.

 

Copper has better conductivity than platinum.

But go ahead and buy the platinum! Some spark plug company corporate executives would really like a new yacht.

Don't believe everything you read on some website. I found a glaring error right in the beginning of this article:

"Electrons leap away from the tip of a small-diameter, sharp-edged wire far more willingly than from one that's fatter and rounded."

On negative-ground cars, the ground electrode is negative, and the center electrode positive. Anyone who knows anything about electricity knows that this means the electrons are "leaping" away from the ground electrode, not the center one. Of course, this elementary stuff really doesn't cover much of what really happens in electric arcs, which involves plasma.

The most important thing about spark plugs is that arcs are more easily created between sharp points, so rounded electrodes on a spark plug equals a poorer performing plug. Of course, regular $2 NGKs start out with nice sharp electrodes, which wear away with use.

So, the simple answer here is that the $2 plugs are fine, but you have to replace them more often. If you're the type of person who takes his car to the dealership to have the plugs replaced, it's to your advantage to spend 4-5 times as much for the platinum plugs, because you won't have to replace them as often (= big savings in labor costs). Does anyone here actually do this? For the rest of us who do it ourselves, we can save a lot of money by using the cheaper plugs and replacing them every 20k.

i dont think you'll be able to buy a yacht selling spark plugs, but then again......lol

You don't think the executives of companies that sell tens of millions of spark plugs every year (along with various other components they manufacturer and sell to OEMs and distributors) can afford a yacht? I don't know what you're thinking, but most corporate executives make upwards of $1 million a year, sometimes much more after bonuses and stock options. With the probably higher profit margin on "high-end" spark plugs, that means more profit for the company, and a bigger bonus for the executives. I think I'll change my plugs a little more often and save up for my own yacht instead of helping to finance someone else's.

 

I have run only NGK copper plugs for over 100K miles now, and I change them every 10K-15K. It takes all of 5 minutes to do it.

 

Anyone ever see the plugs on this site?
