Bosch Motorsport electronic throttle bodies (ETBs) are designed to control the fresh air delivery of spark ignition engines in combination with an electronic throttle control (ETC) system. ETB applications with flex-fuel, CNG and LPG are permissible if injected in the air flow after the throttle body. A typical ETC system includes the following components: electronic throttle body, accelerator pedal module, and electronic control unit. Additional features of Bosch Motorsport electronic throttle bodies include: * Many bore diameters available * Opening direction: most are counterclockwise; select ETBs are clockwise * Two redundant sensors control the throttle position * All ETBs have an idle air position * Temperature range: -40 to 284 degrees F (-40 to 140 degrees C) * ETBs can be connected directly to control units with ETC functionality * Supply voltage: 6 to 16 V * Supply voltage sensor: 5 ± 0.2 V * Output signal I: 0 to 5 V for 0 to 90 degrees * Output signal II: 5 to 0 V for 0 to 90 degrees

Fuel pulse dampers, or pulsation dampers, act in tandem with the fuel pressure regulator to ensure stable and consistent fuel delivery to the engine. They do this by smoothing out the pressure fluctuations, or pulsations, caused by the injectors opening and closing, as well as the fuel pump operating. AEM Electronics fuel pulse dampers feature billet aluminum construction with an anodized finish and are ideal for applications with large fuel injectors and high-volume fuel pumps. They are compatible with any fuel and available as a direct-mount or in-line style with a standard or extended psi range. Select the best fit for your fuel system.

You don't have to suffer constant carburetor issues in your hot rod or race car anymore. K&N Electronic Carburetor Injection (ECI) are self-tuning bolt-on systems that add a supplemental fuel source to optimize engine performance. And, since they are supplemental systems, you can tap into your current fuel supply and there is no need to run a return line back to your fuel tank. Users have the option to set detailed parameters, including their desired air-to-fuel ratio, injector pulse width, shot volume, progressive injector firing, and minimum/maximum rpm range. The brain of K&N's ECI systems is the ECU, which vigilantly monitors the input from the oxygen sensor to ensure an optimal air-to-fuel ratio is maintained. If the system detects an AFR higher than the user-defined limit, the injector will fire. Unlike a typical electronic fuel injection system, the ECI works cooperatively with your existing carburetor, supporting the fuel flow rates that high-horsepower vehicles require to operate efficiently. If your engine is performing lean, K&N's ECI systems will help make up for the fuel deficit. The kits include everything you need to get started: * Billet aluminum carburetor plate with fuel rail and gaskets * Fuel injector * Oxygen sensor * Injection-molded ECU * Fittings and hardware * Wiring harness Features: * Throttle linkage is unaltered from existing setup * Low-profile plate doesn't add much height under the hood * ECU is weatherproof and small enough to be mounted just about anywhere * ECI wiring harness comes with all connections pre-terminated and each connector is unique, so it only fits one way * Harness is pre-wrapped in wire loom for a seamless look with your existing vehicle wiring harnesses * Installation and tuning are easy
