Re: thiughts on ngk iridium plugs Before you install them...take a look at your TR6s. Compare the threaded area....the Irridiums I had did not thread all the way down and would have been only half way down into the combustion chamber.
They were Denso Irridiums ITR 20 or something like that.
Other than that Ive heard they are a good plug..give am shot if they are the right ones.
