High Performance BMW Fuel Injectors

A failing fuel injector can significantly affect your BMW's performance, fuel efficiency, and emissions. Here are some common signs to watch for:
1. Engine Misfires: A failing injector can cause the engine to misfire, leading to rough idling, a decrease in power, and an uneven running condition. This is because the injector is not supplying the correct amount of fuel to the engine.
2. Poor Idle: If your car is idling roughly or unevenly, it might be due to a dirty or failing fuel injector that's not delivering the proper fuel spray pattern required for efficient combustion.
3. Reduced Engine Power and Acceleration: If a fuel injector is not delivering enough fuel to the engine, you may notice a lack of power or a decrease in acceleration.
4. Increased Fuel Consumption: A malfunctioning injector can cause your vehicle to consume more fuel than usual. This is often because the injector is stuck open, leaking fuel, or not atomizing the fuel properly.
5. Engine Knock or Detonation: This can occur when the fuel mixture in the engine's combustion chambers is imbalanced due to an injector delivering too much or too little fuel. This imbalance can cause knocking sounds or a pinging noise from the engine.

The difficulty of installing injectors can vary depending on your BMW model and your personal mechanical experience. We recommend checking in with a qualified mechanic if you're unsure about tackling the installation yourself.

If you need to replace an injector for any reason, you will still be able to keep a tightly grouped set of injectors. The information and flow characteristics of your injector set are stored on a cloud server, and we know exactly what your replacement injector needs to do to match the injector set you have in your car. We simply pick an injector that falls within 1% flow and 2% dead time of your set, and it will fit seamlessly without the need for a retune.
