Hey guys i was just wondering what spark plugs i should put in my truck its still new only 6500 miles but i just put in a banks cold air and throttle body spacer...the reason why im asking is because i put those bosch platinum 4's in my dodge 3.7l and it caused a rough idle figured id ask before i buy thanks

 

I'd stick with what came from the factory, Champion spark plugs. I've heard of people having issues with other brands. not sure why Chrysler likes Champions so much but they do.

 

yup, what he said. they are what we use in our jeeps
