    Core Charge

    Send your old injectors back to Exergy Performance. After a quality control inspection, your core charge will be refunded. We have separated the core charge out in our product bundle so you can clearly see the cost of injectors before and after this fee. The core charge is not optional, your injectors will not ship without this charge being collected.

    Strongly Recommended Additions

    New Injector Lines

    We strongly recommend, almost insist, that you replace the Injector Lines. You are making an investment in high quality injectors. “Cheaping out” and not replacing these lines is penny wise and dollar foolish. The only reason we have it as an option in this bundle is to show you the price breakdown of the full job.
