What is the best all around spark plug to install in a two wheel drive F-150 302 cubic inch with an automatic transmission?

I'm looking for good gas mileage and even power during normal driving.

not sure what the best all around is but I really like NGK

NGK are great. Bosch used to make a good spark plug but i dont know about now.

 

Thanks. I'm going with Autolite Platinum AP 25.

I use AC rapidfire. Great plugs. They also last a while.

 

does anyone know the gapping for plugs for a 5.0?

 

40-45

 

how hard is it to replace the plugs closest to the firewall? never tried but seems really tight.

1995 302 cie. 2wd automatic.

 

Fairly easy. Probably need a 4" or so extension, also the gap should be on the valve cover or radiator support emission tags, usually .45. I gap mine at .50 with no problem. Plugs come out clean.
