What is an ITB? On your factory car, exists a single throttle body in which the air travels through before reaching the combustion chamber for its part in the bang. A throttle body, acting as a valve, regulates the mass of air entering the intake manifold, …

當談到引擎進氣系統，無論是使用自然進氣設計或者增壓設計，獨立式節氣門系統 Individual Throttle Bodies (以下簡稱 ITB ) 的油門反應與效率始終有著不敗的地位。

2024年10月10日 · Individual throttle bodies, as the name partly implies, involve using a throttle body for each cylinder, all linked by one throttle cable. Where an airbox is used, it contains...

Individual Throttle Bodies (ITB's) offer significant performance advantages for your engine. They provide a prompt response to throttle inputs, improving overall drivability and performance, especially in dynamic driving scenarios.

Jenvey Dynamics design, develop and manufacture fuel injection (EFI) throttle bodies (ITB) and induction systems for all levels of motorsport from road going sports cars, kit cars and track day vehicles to World Superbike, S2000 spec Rally cars and World and British touring cars.

Individual throttle bodies (ITBs) refer to an intake arrangement where each engine cylinder has its own throttle body, instead of relying on a single large throttle body and common plenum chamber for all cylinders, as you’ll find in the vast majority of vehicles.

V8 Stack Injection describes any ITB or multi-throttle intake system, which not only look and sound great, but also offer the very best in engine response.
