The bottom line is K&N's are no different than Slick 50. Engineered engines don't leave HP pinch points in the air filters. Worse, the oil can cause MAS contamination over time which would then require extra maintenance. As as far as the Dodge, if it was an electronic throttle body, I suppose gunk (from some source, not necessarily the K&N) could restrict the TB and cause problems.
