This might be a dumb question but when you upgrade a trucks tune or put in a tuner like the edge should you also upgrade type of spark plug or the coil on the ignition. I have found several different coils and plug options but im not sure if they are worth the money im not really interested in more performance but more reliability while using my Edge evolution.

 

No, not necessary at all. There really isn't a good plug alternative at this point.

 

Brisk plugs are supposed to be decent but you are supposed to change them every 20,000.
