How often should I replace Iridium spark plugs?
How Often Should I Replace Iridium Spark Plugs? Conventional spark plugs should be replaced every 20,000-50,000 miles. Iridium or platinum-tipped spark plugs – also called “long life spark plugs” should be changed 60,000 and 150,000 miles, depending on the owner’s vehicle.
Do Iridium plugs make a difference?
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency.
Do Iridium plugs run hotter?
Spark plugs with a hotter heat range will burn off carbon deposits more easily than a colder plug. “As an example, an Autolite copper 105 versus an XP Iridium 105 will have identical ceramic temperatures and the carbon burn off will be the same,” says Reeves.
What is the lifespan of Iridium spark plugs?
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.
Can I use platinum spark plugs instead of Iridium?
Platinum may be harder than copper, but iridium is the hardest among the three, and iridium spark plugs outlast platinum spark plugs by almost twice the mileage. … Platinum spark plugs offer a slightly cheaper but less reliable option if you don’t want to spend as much on iridium spark plugs.
Should I use a hotter spark plug?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean may contribute to pre-ignition or detonation. If not running an electronic engine management system, it pays to tune slightly on the rich side to avoid detonation.
What’s the advantage of Iridium spark plugs?
Iridium Plugs improve the engine performance in terms of power. The extra power becomes apparent in situations like climbing hills, giving you a comfortable driving and touring experience. The ultra-fine center electrode of an Iridium Plug ensures fast ignition and improves the engine’s starting characteristics.
Which spark plugs are best for fuel economy?
5 Best Spark Plugs for Gas Mileage and Performance#1 – NGK G-Power Spark Plugs.#2 – NGK Iridium IX Spark Plugs.#3 – Bosch Double Platinum Spark Plugs.#4 – Denso Platinum TT Spark Plugs.#5 – Motorcraft Platinum Spark Plugs.

It is recommended that you double check the gap on any spark plug before installation to assure the proper gap for your application.
Do NGK Iridium spark plugs increase horsepower?
Increase your performance. Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more horsepower.
What’s the best spark plugs for horsepower?
The advantages of high-end spark plugs The best spark plugs for horsepower are either made out of platinum or iridium, although spending a little more on iridium spark plugs can turn out to be a better investment in the long run.
What happens if you don’t change your spark plugs?
Spark plugs will deteriorate over time, so if they are not replaced, various engine issues will arise. When the spark plugs do not spark adequately, the combustion of the air/fuel mixture becomes incomplete leading to loss of engine power, and in the worst case scenario the engine will not run.
What happens if you gap spark plugs too much?
However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.
Can you clean Iridium spark plugs?
A good set of spark plugs will give you about 20,000 to 30,000 miles. … Using sandpaper to clean an iridium spark plug could potentially damage the tip of the plug.
