tailieunhanh - Spark plug technical information (whitepaper)

The performance tuning industry is brimming with misinformation regarding spark plug center electrode design, with perhaps the largest misconception of all being that because copper is a better conductor than iridium the so-called “copper” spark plugs offered by many manufacturers are also somehow superior. It is true that copper is superior to iridium in its heat and electrical conduction capabilities, however it is also a completely unsuitable material to be used as a high voltage electrode, and it not used as electrode material on any spark plug. The socalled “copper” plugs often spoken about use copper “plugged” nickel/chrome alloy for the center electrode. |
