The forum talks about the above spark plugs. I can get Bosch Platinums free from a friend who can't use them anymore (doesn't have the vehicle). If they are the right part number, are these ok for a Hemi?

Thanks anyway...he lifted my spirits just to let them crash miserably by not have the right part number. Oh...and I'm just over the line from you in Purcellville.

It was probably for the best. The Hemi doesn't really like anything but the factory copper type plugs. :)

Brad, I've searched and read quite a few plug threads here, but I've yet to see a confirmed mechanical reason why precious metal plugs aren't compatible with our hemi. I'm not saying they're compatible or making it an issue of argument. I'm just wanting to know what the reason is. I may have missed the thread where the issue was confirmed...maybe even by Dodge. I've seen some threads where some claimed the precious metal plugs gave them operational issues. Again, not arguing against that. But why exactly?

I'm no ignition engineer by any means, but I've done quite a few ignition mods on trucks, hotrods, and motorcycles over the years, and I find it fascinating that our hemi allegedly won't run precious metal plugs.
