This kit came with everything needed to do a quality repair. The injectors are nice because they are new and not re-manufactured.

These things perform better than I expected. My balance rates are amazing, and the truck never skips a beat. I couldn't be happier with my purchase!

Wow What great customer service. I called twice asking questions and got straight forward answers no pressure sales. Then decided to purchase eight fuel injectors and deluxe installation kit on next phone call. I watched videos and ask questions everything for me went smooth I have a stock lb7 fuel mileage is at high teens in town and low to mid twenties on highway196500 on odometer at first change of injectors I like the thought of matching injectors only wish the test results came with the the quality injectors all packaged and capped in a quality heavy MA box All I can say is great job for M A well worth the phone calls thanks again
