How often should iridium spark plugs be replaced?
Replacement spark plugs should usually be the same type (platinum or iridium) as the original if they are expected to last 100,000 miles. Standard spark plugs are only good for about 40,000 miles. On some applications, a double-platinum or double-iridium spark plug may be recommended.
How long will iridium plugs last?
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium Spark Plugs have iridium center and a platinum ground electrodes.
Do iridium spark plugs go bad?
Iridium spark plugs – Lifetime Symptoms of worn spark plugs: A few misfires (but with no ODBII code generation) upon slight acceleration from speeds between 40 to 60 Km/h. Fuel consumption increase. Rough idle when engine is cold, although this symptom is common to so many other failures.
How long do NGK Laser iridium plugs last?
These two plugs perform similarly, due to their fine-wire tip design, but the service interval is different; the Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium IX® spark plugs are designed to last 40 to 50 thousand miles.
Are there aftermarket plugs for iridium spark plugs?
Fitting an aftermarket Iridium plug may actually result in a drop in performance and service life. Denso’s Tough Plug design combines an ultra fine 0.4mm diameter centre electrode with a platinum ‘chip’, embedded in the ground electrode. High quality materials are use throughout.
What are the different types of spark plugs?
Spark plugs are made of different types of materials. Copper, iridium, and platinum are common metals used in manufacturing them, and all have different lifespans. Copper is good for electrical current, but doesn’t last as long as both iridium and platinum.
How often should you change your spark plugs?
Many mechanics and manufacturers are beginning to set 80,000 miles as the new standard for the industry, but most mechanics still suggest changing them sooner. Most manufacturers advise that you can travel at least 80,000 miles before a change is required for the newest vehicles.
What happens to spark plugs as they get older?
Unfortunately, there is no single answer to this question. As spark plugs grow older, they lose their sharp edges as material from the center and ground electrodes is slowly eroded away. As the gap between these two points grows, the voltage required to bridge the gap increases proportionately.
How long does a Denso iridium spark plug last?
Therefore, NGK gives them a life expectancy of 40-50k miles and Denso assigns a recommended replacement interval of 30k miles. OE Iridium Long Life Plugs NGK Laser Iridium and Denso Long-Life Iridium plugs feature an iridium tipped fine wire center electrode, and platinum tipped ground electrode.
What kind of spark plugs have Iridium in them?
OE Iridium Long Life Plugs NGK Laser Iridium and Denso Long-Life Iridium plugs feature an iridium tipped fine wire center electrode, and platinum tipped ground electrode. Bosch Double Iridium includes places iridium in the ground electrode inlay as well.
How often do spark plugs need to be replaced?
Conventional spark plugs need to be replaced every 30,000-50,000 miles. Recommended replacement intervals for iridium- or platinum-tipped spark plugs vary between 60,000 and 120,000 miles. Old spark plug covered in deposits and a new spark plug. You can find the exact interval in the maintenance schedule for your car.
How long will NGK Iridium plugs last for?
A traditional IX iridium plug such as NGK ZFR6FIX-11 has an iridium Center Electrode, however the ground electrode is a traditional nickel construction. Therefore, the ground electrode will wear out first. NGK gives them a life expectancy of 40-50k miles.
