not too keen on the idea my self as it looks like the points could burn out quicker, if you read it it says that the spark will find the best path to travel through?? so it doesnt spark from all 4 points.

any opinions on em?

I don't know about imprezas but they are a good plug. Had them in my last car, they felt a lot better than NGKs

well i wasnt thinking about using them in my scoob, and just woundered if they were actually any good.

so they are good in some cars but not others, cheers.

dont worry about the plug burning out too fast. the closest electrode will spark the most until it burns equal in length to another electrode and so on. you have four chances of achieving successful spark.
i use twin electrode coppers in favour of iridiums or platinums but change them regularly
