This service is provided PER EACH INJECTOR. If you have 6 injectors, you’ll need to purchase QTY 6 of this service.

Quad hole nozzle injector (left) vs. single hole nozzle injector (right). Notice the more dispersed pattern of the quad hole unit.


This can cause serious engine trouble — when one injector is flowing almost double the lowest flowing unit. This is why injectors need to be flow matched, not just cleaned.



  • What is turnaround time like? How soon will I get my injectors back?
    • Most injectors are refurbished and shipped within 2 business days. This may be shorter or longer depending on our current work-log, but should never take more than 5 days. The return shipping time is dependent upon which shipping method you choose at checkout.
  • What happens if one or more of my injectors are faulty or no longer operational?
    • We cannot make a completely broken injector work again. Well, we can, but it would take longer and be more expensive than simply buying a brand new injector. If an injector in your refurbishment order is found to be bad, we will refund or issue a credit for the cost of that injector sans testing material used ($2.50).
  • Do you offer injector replacements?
    • When available or in stock we can offer replacements for broken injectors, however we do not stock every injector and this is subject to availability.
    • Otherwise, please check the injectors section to view our current retail stock.
  • Will you provide information on how the injectors work?
    • Of course, all refurbished injectors include a complete write-up of their flow values so that you know what’s-what. Recommendations will be given when necessary on which injector should be placed at which cylinder to compliment your engine’s flow dynamics.
  • Why does the metal-body service cost more than the plastic-body service?
    • Metal-body injectors also get sanded, polished, and (re-)painted with high-temp rust-proof paint, which takes hours longer to complete.
  • Please ASK any questions you have BEFORE purchasing this service!
