Spark Plug Analysis

[Scot]

I was bored and just wondering how my plugs were looking since I have not checked them in a while. So I pulled out number one and this is what I found..

These plugs have been in the car since the build over a year a go, a blown turbo, and still seems to be peforming well. I have been boosting up to 1.2 bar... just fyi

Analysis from those that know is appreciated. They are NGK R5671A-7....

Thanks

Those look fine to me, touch of carbon deposits but thats because its a turbo car and your running a little rich for safety. Given theyve been in there for a year I would say you have a healthy motor with a good tune. I'm interested to see what some of the more experienced guys say.
