・ITV20 Select a product . There are some differences here, but as many manufacturers believe, they are significant. The Iridium IX ® spark plugs are a single precious metal aftermarket performance plug. That’s why spark plug replacement is carried out at 3-4 MOTs, namely 45,000-60,000 km. As I wrote above, all cars have specific ignition coils, different compression ratios etc. That’s what made copper spark plugs one of the best. In fact, it’s 6 times better compared to other Denso plugs and is 8 times stronger compared to platinum plugs in the market. The nominal life span of iridium plugs can be 120000 miles with negligible amount of degradation. Iridium spark plug life span? Buy online, pick up in-store in 30 minutes. Passenger and Commercial. What is my personal conclusion. Search by vehicle manufacturer item number, Inspecting and Exchanging Plugs / Sevice Life, Regarding the spark plug replacement timing. You receive more durability with iridium spark plugs. If you decide to replace your spark plugs I’d go with iridium spark plugs so that you likely won’t have to worry about replacing them again, at least in that car. Still can’t decide? I have experience with such an element, and therefore there is something to tell and show, let’s think about the pros and cons. Platinum spark plugs have a long service life, but low power. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions. Benefits. Well, and finally, I want to tell you about my experience using (so to speak, leave a review). This is common too – but why?

That is, the distance between the electrodes lasts for a VERY long time, many are talking about 100 – 150,000 km. If you continue to use this site we will assume that you are happy with it. In particular, for vehicles with emissions controls, misfiring can damage the catalytic converter, so using a spark plug all the way to the end of its physical service life is inexpedient economically. If you don’t replace the spark plugs in time, or if you don’t adjust the gap correctly, the ignition coil may fail (because it needs more strength to “break” the large height between the electrodes). Commercial and Industrial. WHERE IS THE TRUTH? They simply will last way longer and will not degrade sooner than copper plugs but still when it comes to performance improvement, copper plugs performance better than iridium or any other plugs out there. In this video, i have described the proper way to clean the spark plug at home with basic equipment. BMW 3 Series E90/E91/E92/E93 Review, Engine Specs And History, Jaguar S-Type Review Specs, Engine, Pros And Cons. There was no power increase and decrease in fuel consumption that the manufacturer had promised. And even if you pour bad gasoline – the spark plugs is covered with a coating (say, red from additives) or carbon deposits, then everything needs to be put on top of a new one. Machine rolled threads prevent seizing or cross threading during installation and removal. FREE Shipping by Amazon. Failure due to sparks not discharging between the electrodes of the spark plug. Nevertheless, I expect them to last at least as long as the Iridium Laser plugs. Spark plugs are an important element in a car engine. Two electrodes, opposite each other. The electrode progressively wears, causing the spark gap to increase, along with the increasing number of spark discharges. [Examples] Although in fairness it should be noted that some manufacturers call the iridium option platinum, or cover the point of contact with platinum using a similar technology to iridium (this is not the point now). Per NGK, G-Power Platinum plugs are good for 60K km, Iridium IX 100K km, and Iridium Laser 120K km. After that, the main factor is the enlargement of the gap due to electrode wear and the rise in the required voltage is smaller. In order to reduce the amount of this wear, nickel alloys, platinum, iridium, and other such materials are used for the electrodes and service lives are also extended with fine electrodes. From the factory, not only the gaps are strictly defined, but also a certain resistance is selected (around them a little lower) so that the ignition coil can “break through” and provide the necessary strong spark. A very hard, refractory, silver-white transition metal of the platinum group. The electrode wears from the locations that discharge easily with spark discharge. Thank you for reading our article and hope you enjoy it. Iridium TT feature the world’s smallest 0.4mm iridium center electrode and 0.7mm needle tip ground electrode, which minimize spark interference and maximize ignitability, resulting in better power, torque and fuel economy. 　・IKH20　　　　etc. Even though different manufacturers produce them, you’ll still receive an average of 50,000 miles before the new units require service. The strength, hardness and high melting point of iridium makes it very well suited for a fine wire plug and ultra long life spark plugs. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. Save on Denso Spark Plug Iridium Long-Life (SK20R11) 3297 at Advance Auto Parts. High Performance Spark Plugs and OE Replacement. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. But guys, in fact, this doesn’t make any sense. 　・IK20 The ground electrode will wear out first. But the cost is expensive. 　・VXU22 This rise in the required voltage is large until the sharp section at the end of the center electrode is worn round to some degree (about 4,000km). This can lead to carbon fouling or oil fouling. At first I wanted to tell you a little about iridium and platinum. So, an investment in these spark plugs would surely be worth it for this. In particular, since the center electrode reaches high temperatures, it oxidizes and wears. Please submit in the comments, so that our other friends can find out.
