Personally I wasted the $160 to purchase the 4-pack of Mopar Performance injectors. (P4452804)
My fuel mixture did not improve one iota. If you own Turbo II injectors already do not waste your money.As you can see by the chart, they are nothing more than stock replacement injectors!
At one time Mopar Performance sold the higher flowing injectors (803 & 804), that were nothing more then the injectors that failed Chrysler quality control because they flowed to much. As the stocks of these injectors were depleated they were replaced with stock flowing injectors.
