Yes, but they are an expensive plug, youshouldhave no problem with std copper stuff in right heat range

well for anyone that might be curious, ran the it22 denso plugs gapped at .042 for the first two runs on thur , and then inspected them and regapped to .040 for the next 3 runs. all runs were on a 150wet. i did have the timing set back safe to around 13-14* until i get the fuel right with the nano and my a new ve map that i'm experimenting with. on the average the fuel was 10.5.. the heat ring was closer to the tip and i used 110unleaded. any suggestion are welcome. thank you.

Get a non projected tip plug. You stick your arm out in the fire yor gonna get burned.

thank you, sir. gotta search for the part #. did you personally have the projected type denso and failed on you or you know of someone? i know the nonprojected tip is by far the way to go but supposedly thet are horrible for idle cuase they faoul out. but i'm willing to experiment.
