Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling.
How often should platinum spark plugs be replaced?
There are two types of spark plugs: conventional and long-life. Conventional spark plugs need to be replaced every 30,000-50,000 miles. Long-life (iridium- or platinum-tipped) spark plugs need to be changed between 60,000 and 150,000 miles, depending on the vehicle.
How many miles do double platinum spark plugs last?
The answer was double platinum spark plugs, which have a platinum ball welded to both the center and side electrodes. This provides excellent durability with very little gap growth up to 100,000 miles. Vehicles with DIS ignitions should always have plugs replaced with double platinum spark plugs.
What is the main disadvantage of platinum spark plugs?
Single platinum spark plugs feature a platinum disc welded on the center electrode, while double platinum spark plugs have platinum discs on the center and side electrodes. The only drawback of platinum is that it’s less conductive than copper, so it is inferior to the latter when it comes to performance.
How long does an average spark plug last?
A standard copper spark plug has an average life span of 10,000-20,000 miles. Silver plugs, used for older vehicles, can last up to 20,000 miles. Expensive iridium spark plugs or platinum spark plugs can last 60,000 miles. Extended life spark plugs or long life spark plugs can last 100,000 miles.
Which is Better double platinum or iridium spark plugs?
What’s Better, Double Platinum Or Iridium? In comparing double platinum with iridium, iridium has proven to offer more benefits than platinum. The power of iridium spark plugs makes them 25% longer lasting than platinum spark plugs. Thus, iridium can be concluded as the superior material.
Are double platinum spark plugs better?
Double platinum spark plugs have platinum coating both the center and ground electrodes. This is more efficient and longer-lasting which makes these plugs a great choice for a wasted spark ignition system, which exerts more wear on both electrodes than do other ignition systems.
Can spark plugs last 200 000 miles?
Spark plugs If maintained well, they can last 100,000 miles. But by the 200K mark, you could be overdue for a third set of plugs. Cost to replace: $100 to $300.
How do I know if my spark plugs need changing?
8 Signs the Spark Plugs or Spark Plug Wires Need Replacing: Regular Maintenance. Check the owner’s manual for the replacement interval. Spark Plug Wires. Fuel Economy Degradation. Slower Acceleration. Rough Idling. Engine Misfires. Difficulty Starting. Warning Lights.
Are platinum plugs better than copper?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. Platinum has good longevity and the worst performance.
What is the best spark plugs on the market?
Original Equipment AC Delco : Best Spark Plug Overall. Denso Iridium TT : Best Overall First Runner Up. E3 Diamondfire : Best Performance Spark Plug. NGK Spark Plugs : Best Standard Spark Plug. Champion Copper Plus : Best Small Engine Spark Plug.

Can I use platinum spark plugs instead of iridium?
Iridium is harder than platinum, and in most cases, iridium spark plugs last about 25 percent longer than comparable platinum spark plugs. So you do the math on which is better for you, other than that there is no effect.
How long do Mercedes spark plugs last?
San Diego Mercedes-Benz drivers often ask us, “When do I change spark plugs?” Experts typically recommend replacing them every 30,000 miles, although that distance interval can fluctuate depending on the model you drive.
How often should I get a tune up?
Most older vehicles with non-electronic ignitions should be tuned every 10,000 to 12,000 miles or every year, whichever comes first. Newer cars with electronic ignition and fuel injection systems are scheduled to go from 25,000 miles to as many as 100,000 miles without needing a major tune-up.
Do spark plugs age out?
But unlike some of our devices, ageing spark plugs might not be very evident for a layman. As spark plugs go through thousands and thousands of miles along with your vehicle, their internal components tend to wear out and even though they can withstand extreme temperatures, their durability goes down with time.

What spark plugs are better than NGK?
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.
Can spark plugs increase horsepower?
