ive always put NGK TR55s in both of my stangs, but this time around all they had were the champions. i put those in for now, and it seems to like them a lot better... idles much smoother and runs through the rpms cleaner. just thought i post this since i know most run the NGKs.

 

NGK FTW.

I have a hard time seeing anyone being able to tell the difference (how it runs wise) in spark plugs though. You replaced the plugs and it runs better? Was there any damage on the plugs etc?

 

no the thing that made me realize this time is that whenever i change the plugs, i never notice a difference, but this time i did for some reason. maybe it could be a combination of things... because i changed the posotion of my MAF sensor as well to 12 o clock now that i think about it lol

 

i run champions in all my cars and havent had a problem. that is what i am curruently running and seems to like just fine. ive rarely been able to tell a difference in just plugs alone so maybe the car is a little pickey
