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. Iridium-tipped spark plugs offer better power, more complete combustion that leads to smooth-running engines, and a longer lifespan than copper/nickel plugs. 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. In the 1970s, whether you rode a bike with a four-stroke or two-stroke engine, spark plugs introduced themselves into your riding life much more often than they do … Aftermarket Long Life Iridium Plugs Autolite Iridium XP, Champion Iridium, Bosch Iridium and Denso Iridium TT bring the features of OEM iridium long life plugs to the market, with an iridium or iridium enhanced fine wire center electrode and platinum or iridium/platinum tipped ground electrode. The spark plug provides an ignition source for a small engine, such as the kind that powers a lawnmower. Platinum is much harder metal than nickel alloy and has a higher melting point. It is estimated that iridium spark plugs will last for at least 60,000 miles. Our Ford Territory is now 7 years old and approaching 100,000km. Dual-Ground Electrode Toyota Spark Plugs. 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.
