Hey ya'll,

I have had my expy EB now for a year and have run it up from 82,000 to 105,000 I have started to notice a little bit of a rough idle, and by the looks it is still running the factory cops and plugs. I am going to change out the plugs with Motorcraft because I have heard these motors are kinda picky ( thought about the E3's but a buddy put them in his 4.6 worked great for about 2 months and then he ended up pulling them because it was running worse than before he installed them.) But my main question is has any one on here tried the Granitelle or Accel COPs, or should I go with the E Bay special on the stockers for the v -10 so that I have a couple extra? Any input would be greatly appreciated.

Jason
