A0010172121 makes Bosio different?
-Tighter Internal Tolerances
-High grade modern metal alloys
-Hardened needle increasing needle life
-Nanometer tolerances increasing nozzle efficiency
-All nozzles and internal components are cast, and machined in house (Italy)
-Latest generation metallurgy using the most advanced machining processes

New nozzles require more than just a vice, a wrench and a little luck.

Protect your investment and have your new nozzles Professionally rebuilt and properly mounted.

“But why should I pay for somebody to install my nozzles, since the engine runs when I have put them on myself without having to set them in the past?”

Well, We don’t just slap on your nozzles and hope for the best. We start by completely stripping your old injectors of rust and corrosion, followed by ultrasonic cleaning all the parts to remove every possible contaminant and prepare the parts for the next step in the process. We inspect every part and resurface all the internal contact areas to insure a leak-tight seal against the high pressures of your fuel system.We don’t stop there, We then build-up your new injectors one at a time to achieve the tightest tolerances which easily exceed the original specifications when new. We insure that there is no leakage acrossthe high pressure contact faces, including the mounting plate and retaining nut.

We don’t use your Father’s 1920’s bottle jack style pop-tester, We go further, a LOT further by utilizing modern state of the art high speed digital calibration equipment to precisely set your injectors to insure the most precise sequencing cylinder to cylinder.

Our shop is unique in that we have the original “Fine” tolerance shim kits that allow us to set your injectors to less than 1 bar maximum deviation tolerances unlike other shops who typically have the coarse shim kits that only allow 8-10 bar adjustment increments.

After your injectors are completely rebuilt, set, adjusted and pass all injector tests, we completely re-coat your injectors to insure your injector assemblies remain corrosion/rust free until their next overhaul.

What our service gets you is assurance that you will get the maximum life out of your injectors. Our strict tolerances reduce displaced volume lost to the fuel system via the return lines, lowers pump stress by insuring the fuel pump only displaces what is needed to pump fuel to the cylinders thru the nozzle. Additional power is typically gained since peak delivery efficiency is often improved by as much as 30%. Greater efficiency is realized since the injectors work in perfect harmony cylinder to cylinder, and flow balance is optimized equalizing cylinder pressures which promotes greater combustion efficiency transmitted to the crank. In all cases the precise settings we employ save you money and gain you better fuel economy. Most if not all customers see reductions in turbo temperatures and less heat lost to the cooling jacket thanks to more efficient combustion and losses to the pre-combustion chamber ultimately lowering the wear and tear on your motor.

All injector rebuilds include new heat shields and Braided fuel return lines.

1 3 Year Unlimited Mileage Warranty requires installation and injector overhaul by our shop. Wear caused by use of fuels other than ULSD, Commercial BioDiesel (up to B100) will not be covered and are sold as is.
