i know when i asked the dealer for the plugs alone they came in just over $100.00cdn for all 16 and that was at 10% above cost i didnt think to ask what the labour is on that i rather do all that smaller things my self when i can. i havent gotten around to that yet but judging from what you found my top row is overdue hmm git er done i guess. oh and not sure why the change but i was told by a service rep that yota runs the bosch from factory and they hold up really dunno what thats gott do with the price of tea in china though just what i was told whrn i asked

 

I was just doing my spark plugs yesterday and ****ed the coil up.... A word of advice to you.. The Dodge dealership that I have went to for 2 years now has told me not to use bosch plugs. They have been screwing up the engines in the 08+ daks. I have an 08 Dak SLT with 4.7 V8 Flex and the old bosch plugs i pulled were burnt... the mechanic and very close friend told me to go with the new dodge part # for champion plugs.. OEM and great performance.. Dont want to see a fellow dak owner suffer with a messed up truck
