99s also have the EV6 connector. It's better to seartch either for the injector's manufacturer part# or Ford/Chrysler/Dodge part number. This eliminates the Vehicle/year search which just confuses the hell out of people.
Bosch part number 0280155917 <--- I run these. 3 mpg increase, smoothed out quite a bit and got some "snap". These are 19#/hr for stock 4.0s.
