Yes, the Autolites worked out perfectly. My best run was 87 USmpg (2.7 l/100km). No issues at all. I tried to install a set for another Insight and I ran into indexing problems. Like most Insights, this one was a "B" orientation and only one of the six plugs I had was acceptable. So I have quite a handful of plugs that might work for another orientation. (I think "C" mostly).
