DS 7 Crossback 1.6 PureTech - Iridium Spark Plugs Condition After 80,000 km

[DIY Enthusiast]

I wanted to share a quick video analysis I did regarding the health and longevity of the factory-recommended NGK ILZKBR7B8G (Laser Iridium) spark plugs on the 1.6 PureTech 225hp engine (EP6FADTX) in my DS 7 Crossback.
The manufacturer specifications claim these high-density iridium plugs can last up to 160,000 km (100k miles). However, after pulling mine out at exactly half that lifespan (80,000 km), the real-world wear tells a completely different story.

Interesting, but, in times fine by, you used to check and adjust spark plugs every service. Perhaps that how they estimate that the spark plugs last 160,000 kms.
