Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Unlock more from your JB4PRO with these plug-in add-on harnesses from Nforcd. Each harness extends the capability of your existing JB4PRO setup, allowing you to integrate flex-fuel inputs, support port injection, or add charge pipe injection depending on your application.

Kia 3.3T CPI Harness - Attaches to your existing Kia/G70 JB4PRO harness to enable charge pipe injection (CPI).
