Find Parts That Fit Your Vehicle

Kits

BMW fuel system kits provide a comprehensive solution for maintaining and upgrading the fuel delivery system, ensuring optimal engine performance and efficiency. Over time, fuel pumps, injectors, filters, and pressure regulators can wear out, leading to poor fuel economy, hard starts, misfires, and engine hesitation. Common problems include clogged fuel injectors, failing fuel pumps, and fuel pressure inconsistencies, which can result in rough idling and reduced power. Upgrading or replacing worn components with a complete BMW fuel system kit restores proper fuel flow, enhances throttle response, and improves overall drivability. Our selection of OEM and high-performance BMW fuel system kits includes everything needed for a reliable fuel system refresh, ensuring a precise fit and long-lasting durability for a wide range of BMW models.

Take your B58 or S58 build further with the JB4PRO Flex Fuel Add-On Harness—a simple, plug-and-play way to add an ethanol sensor and optional fuel pressure sensor to your JB4PRO setup. Keep your install clean, your wiring organized, and your tune dialed to match every fuel blend in the tank. Why it matters: Plug & Play: Connects directly to your JB4PRO—no cutting or splicing required. Sensor Ready: Supports ethanol and fuel pressure sensors for precise, real-time fueling adjustments. Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware. It’s not a complete flex fuel kit—you still need a compatible ethanol sensor—but it gives your JB4PRO the accurate readings it needs to adjust timing, boost, and fueling for E30, E50, or E85 blends.
