This premium Port Injection Kit delivers the additional fuel capacity needed to support demanding performance applications without compromising OEM fitment.

Whether you're building for the street or the track, this S58 Fuel System Upgrade offers dependable fueling, precise fitment, and the performance enthusiasts expect from Rvng RaceWorks. Follow Rvng RaceWorks on Instagram to explore customer builds, product installations, and the latest high-performance upgrades.
This kit delivers true multi-port injection and is compatible with all fuel types including full E85. It is available with or without injectors. Injector-equipped kits include genuine Bosch Motorsport injectors that are modified and flow matched both statically and dynamically. Flow data is included to support accurate and consistent tuning.
The RVNG fuel rail features a true full-bore AN6 internal design to prevent pressure drop under high load. Integrated injector retention locks mechanically secure each injector to the rail, reducing stress on the factory plastic intake manifold and allowing the rail to be removed without fuel spill during service.
All fuel lines are smooth-bore PTFE paired with motorsport-grade billet fittings. No rubber hose or plastic fittings are used. The kit includes all required hardware and is compatible with popular injector controllers such as ReFlex, AIC, and JB4-based systems.

FAQs
Answers to our most common questions below.
How Long Does Shipping Take?
All RVNG items ship within 1-3 days. If an item is out of stock the customer will be notified with the choice of a refund or an estimated timeline of delivery.
Do You Have Exhaust Parts For My Car?
We make a range of performance parts but we do not have something for every car. We choose to specialize in specific markets so we can always ensure we are selling the best products possible. As a small company who designs all new products and stocks all our items its hard to sell something for everyone but as we grow we are always looking to expand our catalog!
Do You Offer In Person Pick-Up & Installs In Cali?
Yes, We are located in Garden Grove in Orange County, California. We invite any of our customers to pick-up in stock items and for any install or car related work.
Will Installing These Parts Void My Factory Warranty?
Aftermarket performance parts can affect your factory warranty on related components under the Magnuson-Moss Warranty Act a dealer must prove the part caused the failure to deny a claim. We recommend speaking with your dealer or tuner. Our parts are precision-engineered to factory tolerances and we stand behind every product with our own Lifetime Warranty against defects and fitment issues.
Do These Parts Require a Tune?
Some parts particularly downpipes, intake kits, and fuel system upgrades strongly benefit from an ECU tune to see full performance gains and to prevent check engine lights. Parts like heat exchangers, oil coolers, and hardware do not require a tune. We recommend reaching out to us or your local tuner before purchasing if you're unsure.
What Is Your Return Policy?
We accept returns within 30 days of delivery on unused, uninstalled, and undamaged items in original packaging. Custom or made-to-order parts are non-returnable.
