I‘m getting ready to check the valves in my 2015. I found this thread when researching iridium plugs. It looked like the
CPR8EAIX-9 was the best replacement, but I was confused by the stock numbers which were different depending on where I looked. I called NGK to see what they thought, the guy was super helpful. When he specked the OEM plug out, he came up with the same CPR8EAIX-9. I asked about the difference in the stock numbers, he said the correct number is 95134. He said it doesn’t have the screw on terminal, but he is sending me some. I searched that number and they are available locally, as well as Summit Racing, Dennis Kirk and some others(about $9/ea.). My spark plug knowledge is limited, has anyone bought these from the USA distributors? Thanks
