I also run the R7420 (9 leading, 10 trailing) and they last a damn long time. Over 25,000 km with MANY track days at 16 PSi and recently 20 PSi with water injection. After cleaning the plugs by glass blasting them, I realized I could have reused them even longer. The only sign of wear on them was the rear leading plug had a small 1mm wear point at the end of the top metal piece (not sure the name). I believe that is because of my 1850*F rear EGT's. All other plugs looked almost perfect.
The Greddy one's are easier to find and generally cheaper. They are indeed the same plug, they even have R7420 written on them lol
