The benefits of NGK spark plugs
Modern engines use less fuel while requiring more power, which reduces the lifespan of conventional iridium and platinum spark plugs. The revolutionary ruthenium technology from NGK gives your engine the highest amount of longevity and performance.
What spark plugs surpass NGK in quality?
In our experience, NGK Iridium spark plugs survive for literally years. They have been operating as intended for well over 100,000 miles with no noticeable electrode wear. We had to modify the plug space because the conductor did show signs of wear. The iridium electrode itself seems like it may last the entire life of the vehicle.
The electrode in Denso Iridium spark plugs is significantly thinner than that in NGK. You may argue that the NGK electrodes are overengineered given how long they last and that lowering their diameter would have no impact on their service life.
The Denso iridium spark plugs should theoretically last less time because the iridium electrode is thinner. Will there be a discernible difference? Most likely not.
In any event, according to our experience, iridium spark plugs will survive far longer than platinum spark plugs.
NGK Laser Iridium plugs: Are they worthwhile?
Nowadays, the majority of spark plugs used in gasoline automobiles feature a copper core center electrode. You can decide what kind of material should be used to cover the spark plug electrode. You can choose a platinum or an iridium tip to enhance the device’s performance.
