NGK Laser Iridium spark plugs are a top - choice for great performance and long service life. These plugs are precisely engineered for original equipment (OE) applications and are rigorously tested to meet the highest standards, ensuring top - notch quality and durability. The iridium - tipped center electrode is six times harder than platinum, offering excellent durability. The high - grade pure alumina ceramic and 98% pure copper core in NGK spark plugs prevent overheating and guarantee reliable engine starts. Most of these Laser Iridium spark plugs have a platinum pad on the ground electrode, which ensures even wear in distributorless ignition systems. This part is a perfect fit for several Mitsubishi Lancer models from 2008 - 2010, including the Evolution GSR, Evolution MR, Evolution MR Touring, and the 2009 Ralliart.

Using these NGK Iridium spark plugs is easy. First, make sure your engine is cool before you start. Remove the old spark plugs one by one and replace them with these new ones. Just screw them in gently but firmly, and don't overtighten. When it comes to maintenance, it's a good idea to check the spark plugs regularly, especially if you notice any issues with your engine's performance, like rough idling or hard starting. Also, keep the engine clean to prevent dirt and debris from getting into the spark plug area. If you're not sure about anything, it's always a good idea to consult your vehicle's manual or a professional mechanic.
