As you increase power, your Acura RSX's engine also becomes more thirsty. Fuel pressure and fuel flow is critical for an engine's proper operation and even more so when heavily modified. DeatschWerks fuel rails are CNC'd from solid billet T6061 aluminum and designed to allow higher flow to your Acura RSX's engine. What's more, some fuel rail applications will convert to more common or better designed injectors too! Each DeatschWerks fuel rail is specifically designed to be direct fit for each application. Some fuel rail kits will also include injectors that accompany the rail as well. Direct-fit, high-flowing, and a sleek design make these fuel rails a clear winner!

Key Features:

• Kits are direct fit to each application; note that some kits require specific type of injectors to work.
• Flows much more fuel than stock.
• Engineered for use in both return and returnless configurations.
• Outflows the competition with -8AN ORB inlets and outlets utilizing bore diameters that exceed AN spec by 80%.

Fuel Rail Conversion Kit Notes: DeatschWerks offers innovative rail/injector kits for converting side-feed applications to top-feed. Modern top-feed injectors are easier to tune, less expensive, and flow more fuel than the side-feed alternatives. DeatschWerks Fuel Rail Conversion Kits are engineered as a system where the injector, rails, and mounting hardware all work together to integrate flawlessly into the OE manifold and mounting points.
