I go well over 10,000kms on a set(usually a summer of driving for me). I run torco quite a bit so I change them more frequent due to that, without the torco I would go even longer. With my ported eaton setup I had my old TR6ix plugs in for over 30,000kms and they were still running strong. I have TR7ix plugs now with the 3.4

They are worth the added cost to me as I DD the car during the summer and I couldn't stand that buck/surge tendency going through school zone or playground zones in 2nd gear at a low rpm.
