Suggestions for Plugs

I wanted to get some suggestions for some spark plugs for my 95 4.0. All stock and 150000 miles on it. Want to replace the plugs and get suggestion of something good. In the past I had gotten some plugs that burned hot and screwup some stuff. Autolites, Bosch, Champion, Splitfires etc. Suggestions for a better burn and better performance, Thanks Mike

I was told by my mechanic to use only Champion plugs. These are the stock plugs direct from the factory. And also pass on the stupid platinum plugs. Good old cheap copper core plugs work just fine. Unless you swapped in some high-performance engine; you're just wasting your money.

i put NGK's in my 304 and i like them a lot but i have heard nothing but good things about the champions and they seem to be the general consensus
There's no replacement for displacement.
