Not sure if you need to replace your injectors? We can test your injectors on our Bosch test benches right here in Fargo, ND before you buy. If they are bad, and you do end up buying new or reman injectors, we will waive the testing fee for those replacement injectors as an added Thank You.

We are an authorized full Bosch Diesel Center. What does that mean? It means we have consistently invested and trained to offer the highest quality Bosch service and parts available. We have been Bosch authorized since our founding back in 1952. That is over 65 years of premier Bosch service. Our latest addition to serve you and your Bosch products is our state-of-the-art clean room and test benches that are routinely inspected by Bosch in order to provide top quality service. In that clean room we are able to meticulously disassemble, clean, replace parts, and reassemble your reman Bosch injectors before bringing them over to our state-of-the-art Bosch test equipment. No injector leaves our facility without being meticulously cleaned, documented, and tested to OE specs.

How can you know if they are genuine Bosch injectors remanufactured at an authorized facility like ours? Easy! Every reman Bosch injector get a special QR code either on the injector clip or on a side label. Through the official free Bosch Quality Scan app on your phone, you can scan the QR code and get the needed information on your exact injector. Information includes your IMA/IQA code, the build date, injector number, and serial number! Using that code, we or any other authorized Bosch Diesel Center can see the exact components that were remanufactured in your injector. Ask us about the program and we will be glad to help get you started.

If you have any questions or would like to put in an order, feel free to stop on by to talk to one of our diesel experts. You can also give us a call or even send us a message online!
