Just got my stang and changing everything out before I start driving it around and I am wondering what Spark Plugs I should get. I was looking in Jegs and they have NGK plugs and have all different reaches and different temp ratings (hot to cold). What do the different reaches do and what temp range plug should I get. I have a 88 that has either a 89 or 90 engine in it so it is mass air. The block is stock except for MSD ditributor and wires.
Thanks

 

Just go to the local parts store and buy some Autolite plugs specified in the parts book for the 5.0 HO engine and you will be fine. The reach and heat range will be correct.

 

what plugs would you recomend for a 04 gt??
