The POWERPLUS version incorporates several design changes that provide advantages over the OEM design, including a 50 hp / 80 ft-lb gain over stock.

Internal design changes and proprietary manufacturing techniques ensure tighter tolerances than OEM, for better all-around performance, durability, and reliability than the OEM. Fuel economy is very substantially improved, on the order of 15-20%. The motor runs so turbine-smooth you will not recognize it as the same motor. The change in the truck's character is dramatic.

These are NEW NOZZLES, designed and manufactured from the ground up in the Fratelli Bosio factory. (Most other "performance injectors" on the market are modified take-offs or second-hand re-drills, that were once someone else's high mileage exchange nozzle cores.) There is no core exchange required- you keep your original nozzles, should you ever need to return to stock.

If you have the mechanical ability to remove your own injectors, you can easily perform this nozzle swap yourself, and save serious money. Fratelli Bosio, SRL
