now just a few months later its misfiring again. It is estimated that iridium spark plugs will last for at least 60,000 miles. a month later my truck developed a shudder and when i had my codes ran at Auto Zone they said the code was P0304 (a cylinder 4 misfire) i took the truck to a mechanic and he replaced the spark plug and coil pack. Below are the top 3 benefits of iridium spark plugs. Dual-Ground Electrode Toyota Spark Plugs. This causes a spark in the spark plug, which ignites the mixture of fuel and air in the engine. a mechanic replaced all eight plugs and a new coil pack for the one that blew. 24-06-14, 12:41 PM. Our Ford Territory is now 7 years old and approaching 100,000km. Iridium-tipped spark plugs offer better power, more complete combustion that leads to smooth-running engines, and a longer lifespan than copper/nickel plugs. Depending on application, iridium plugs can even approach the lifespan of some platinum ones. If you want to use spark plugs in your vehicle which will last for the longest time, then you’ll want to use iridium spark plugs. Available for select models, this design has several benefits: Both electrodes have platinum to reduce wear and extend service life. Spark Plug Life Span. Long-life platinum and iridium spark plugs will typically last up to 100,000 miles or longer; provided the engine isn’t using oil or doesn’t spend a lot of time idling. Like other parts of your car, these numbers vary depending on how you drive and how well the spark plugs and ignition wires are looked after. Due to this short lifespan, most copper spark plugs need to be changed every 20,000 miles. It has the original iridium spark plugs and I'm wondering at what point shd I replace them?

Iridium spark plugs - lifespan? Most spark plugs have a factory service interval of 100,000 miles; though some may be as much as 120,000 miles. Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. A spark plug is a fairly simple device. 1) Long Lifespan. The platinum-tipped spark plugs often used in these systems have a 60,000-mile (96,561-kilometer) lifespan. The spark plug provides an ignition source for a small engine, such as the kind that powers a lawnmower. Ignition wires can last twice as long. What is the scoop on platinum spark plugs? Life Span Federal law in the United States dictates that the ignition coil and ignition module on new vehicles are warranted for at least two years or 24,000 miles, whichever occurs first. This u-groove traps the the air/fuel mixture before the spark plug fires, making for a large spark, reducing fouling and making for more efficient combustion. Spark plugs typically have a life expectancy of about 45,000 kilometres. But now, in the 21st century, ignition systems use iridium-tipped spark plugs that regularly last as long as 100,000 miles (160,934 kilometers).
