NGK Laser Iridium Spark Plug for Saab 9-5 Turbo6 (2011)

Built for the 2011 Saab 9-5 Turbo6, this NGK Laser Iridium spark plug, part number 5476, fires the air and fuel charge in each cylinder of the turbocharged V6. It carries an OE quality rating and cross-references to factory part number 12 620 540, the number the plug carries in Saab's parts data. NGK makes it in Japan. Laser Iridium is NGK's iridium plug line, which sets it apart from the standard copper-core plugs NGK makes for older engines. The final-year 9-5 is a low-volume car, so having the factory-matched plug number on hand makes a plug change easier.

This NGK spark plug carries a 24-month or 24,000-mile warranty.

Each plug carries ignition voltage across its electrode gap thousands of times a minute and wears a little with every cycle. Misfiring, a check engine light, hesitation, loss of power, and poor fuel economy are the usual signs that a set has reached the end of its life. NGK advises changing plugs at the manufacturer's service interval and checking their condition for warning signs between changes. Niterra, NGK's parent company, supplies its plugs to vehicle manufacturers as factory equipment and sells the same products to the aftermarket.
