NGK Laser Iridium spark plugs blend high performance and long - lasting durability. Designed for original equipment (OE) applications, they meet the highest testing standards. The iridium - tipped center electrode is six times harder than platinum, ensuring long - term use. With high - grade pure alumina ceramic and a 98% pure copper core, these spark plugs prevent overheating and offer reliable engine starts. Many Laser Iridium spark plugs have a platinum pad on the ground electrode for even wear in distributorless ignition systems. This set fits a wide range of car models from 1989 - 2008, including Acura, Aston Martin, Audi, and more.

Using these NGK spark plugs is easy. First, make sure your engine is cool. Locate the spark plug wires on your engine and carefully remove them. Then, use a spark plug socket to remove the old spark plugs. Before installing the new ones, check the gap on the spark plug according to your vehicle's manual. Place the new spark plug into the socket and gently screw it into the engine by hand to avoid cross - threading. Then, use the socket to tighten it properly. When it comes to maintenance, it's a good idea to check the spark plugs regularly, about once a year or every 30,000 - 50,000 miles (depending on your vehicle). Look for signs of wear, like a worn - out electrode or carbon deposits. If you notice any problems, it might be time to replace them. Also, always keep the spark plugs dry and clean. Don't use any abrasive materials on them as it can damage the electrodes. When storing them, keep them in a cool, dry place.
