Yes, you're right I'm going crazy with the numbers smh, number goes up temp goes down. I meant to say CT05 not 7.
But what you're saying according to chart if RP's are almost like nova plugs then that means compared to OS plugs even the CT05(Hot) is colder then there P5 plug?
So I guess the real question is can I go back to Nova plug or did I mess anything up with the OS plug?
Also I took apart engine. I have two shims .5 and .2 unlike what engine diagram says it should be (.3, .2, .3)
Would removing .2 shim be too much?
Sorry to be a pain but I really appreciate the help.
