CARB Compliance / Exemption Warning: If you live in California and your application for this product is not CARB Compliant / Exempt, then you cannot purchase it for public highway or street use (in that case it could only be used for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street). If your application is not CARB Compliant / Exempt and you're shipping to California, our system will let you know on the final checkout page.As you increase power, your BMW Z4'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 BMW Z4'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!

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.
