I went to the NGK website and I see that they have a iridium plug as well. Has anyone used them? Also this morning I went by Autozone to get some Br7s but they dont sell them. The interesting thing was that the guy tried to sell me the Denso's by telling me that they are made by the same company that makes NGK. Does anyone know anything about this. Are the Denso iridiums the same as the NGK iridiums?

 

JL has the Densos and Sal/PSP has the BR7EFs.

Last time I talked to the NGK Tech he stated the Irdium was only avail for us in a TR-55 equiv, he felt this to be to hot for our trucks and he advised against them . So I took his advice. I went with the TR-6's and they are fine.
