I have tried various different types in my Range Rovers over the years and have never really noticed any huge difference. You seem to get an initial change in performance with new plugs but then I guess that is to be expected.

You should get a cleaner burn and they will last you the life of the Cobra now depending on the amount of mileage you do. The one thing that cleaned up the running on mine was an MSD 6AL - definate improvement in the low to mid range.
All the best
