What is the spark plug model for Peugeot 408?

[OViolet]

Peugeot 408's original spark plug is NGK-ILZFR5B. More relevant information is as follows: 1. The spark plug is an important component of the gasoline engine ignition system. It introduces high voltage electricity into the combustion chamber and causes it to jump across the electrode gap to generate a spark, thereby igniting the combustible mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. 2. Spark plugs can be categorized by material into: nickel alloy spark plugs, platinum spark plugs, and iridium spark plugs. By shape, they can be divided into: standard spark plugs, electrode spark plugs, insulator-protruding spark plugs, seat-type spark plugs, and surface-gap spark plugs. By heat value, they can be classified into: cold spark plugs and hot spark plugs (such as the high-performance iridium spark plugs, which save over 10% fuel consumption, making them excellent for vehicle fuel efficiency). The lifespan of a resistor spark plug is 20,000 kilometers, while the better-quality platinum spark plugs last 40,000-50,000 kilometers, and iridium spark plugs last 70,000-80,000 kilometers.
