Show original supplier description
The PFS B58 Port Injection Kit addresses fuel capacity limitations in high-performance B58 engine builds by offering a robust, plug-and-play solution for supplemental port injection. Buyers can customize the package with optional 550CC or 900CC injectors and a Motiv Reflex controller to suit their specific fueling needs. Installation requires an aftermarket charge pipe, such as a 1-inch longer silicone charge pipe, to ensure proper clearance and compatibility. Please note that this kit is not compatible with 2021+ G-series platforms due to physical interference with the alternator. This product is not for sale or use in the state of California on any pollution-controlled vehicle as per California Air Resources Board regulations. Users should ensure they have the necessary harness for the Motiv controller, which must be sourced separately from Motiv.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
