Individual Throttle Bodies – FAQ

Q: What are individual throttle bodies (ITBs)?

A: Individual throttle bodies (ITBs) are a type of intake system used in internal combustion engines. Instead of a single throttle body, ITBs feature individual throttle valves for each cylinder. This setup allows for better airflow control and improved engine response.

Q: What are the benefits of using individual throttle bodies?

A: Individual throttle bodies offer several advantages. They enhance throttle response, increase engine power, and improve engine efficiency. ITBs also provide better cylinder-to-cylinder airflow balance and can enable higher RPM capabilities. Additionally, they can enhance the engine’s intake sound, giving it a more aggressive tone.

Q: Are individual throttle bodies suitable for all engines?

A: Individual throttle bodies can be used on various types of engines, including both naturally aspirated (N/A) and forced induction (turbocharged or supercharged) setups. However, the feasibility of ITBs depends on factors such as engine configuration, space constraints.

Q: Do individual throttle bodies require any modifications to the engine?

A: Installing individual throttle bodies usually requires modifications to the intake manifold and fuel delivery system. The intake manifold needs to be replaced or modified to accommodate the separate throttle bodies, and the fuel injectors may need to be relocated or upgraded. Additionally, the engine control unit (ECU) may need to be reprogrammed or replaced to properly manage the ITBs.

Q: Can I install individual throttle bodies myself, or should I seek professional help?

A: Installing individual throttle bodies can be a complex task that requires a good understanding of engine systems and tuning. If you have the necessary knowledge, experience, and tools, it is possible to install ITBs yourself. However, it is generally recommended to seek professional help from a qualified mechanic or engine tuner to ensure proper installation, calibration, and optimization for optimal performance and reliability.

Q: What engine control unit (ECU) do I need for throttle bodies?

A: Our throttle bodies will work with all aftermarket ECU’s, we would suggest discussing ECU options with your selection mapping provider as most tuners have a preferred brand which they are most confident with mapping. Some factory ECU’s can be re-mapped to run ITB’s, however re-mapping  of the factory ECU requires special software so speak to an ECU specialist to find out if your ECU is mappable.
