Id tos the bosch plugs no matter what you put in them. I guess NGK should be a whole lot better plug but I would just get motorcrafts instead. Autozones can get them even if they have to be ordered.
No precious metal plugs period. Platinuim, Iridium, whatever. Leave it alone. Your wallet will thank you and your motor won't notice.
As for brands, I prefer NGK but have used Motorcraft with favorable results. The only time I've run Autolites was in a '93 DP Ranger and the electrodes wore funny. Changed plug brands and the problem went away. The edges of the electrodes wore as if they were stuck in a pencil sharpener. After awhile they were pointed instead of flat across the tip. I thought it was a fluke so I bought installed another set. Same results. I don't know that it really mattered performance-wise, but I never bought another set of them.
Everything I own currently runs NGKs with the exception of the wife's '06 Stang for obvious reasons
