What do you guys run??? Have you had any Problems with a plug? Have you gotten better performance or gas mileage from one to another?

Go with Champions.Chysler products run like crap with Bosch.I know about this.Had a miss after replacing the engine,1996 Intrepid and it had Bosch spack plugs in it.Pitched the bosch plugs,installed Champions and ran a lot better.
