Send your injectors

Fill out the form below and download your copy — a filled-out PDF with our shipping address on it. We’re notified right away and will send you a quotation by email or phone, whichever you prefer. Once you approve it, ship your set in.

How It Works

From form to finished set

  1. Fill out the form & download your copy

    Tell us who you are and what you’re sending. You get a filled-out PDF shipping form to keep, and we’re notified at the same time.

  2. We send you a quotation

    By email or a phone call — whichever you choose on the form. No surprises: you’ll know the cost before anything ships.

  3. Approve & ship

    Happy with the quote? Print the PDF, put it in the box, wrap each injector individually, and ship to the address on the form.

  4. We confirm arrival

    You’ll hear from us as soon as your set lands on the bench — and we’ll reach out with any questions before work begins.

  5. Cleaned, tested & shipped back

    We clean, flow test, and verify every injector, then ship them back clean, matched, and ready to run — with before/after test results included.
