Magneti Marelli TB0300 Fuel Injection Throttle Body

The Magneti Marelli TB0300 is a fuel injection (FI) throttle body engineered to OEM specifications for precise air intake control. As a key component of the engine's fuel injection system, the throttle body meters the volume of air delivered to the engine in direct response to throttle input, enabling accurate air/fuel mixture management by the ECU.

Magneti Marelli is a globally recognized OEM supplier with extensive expertise in powertrain components, including throttle bodies, injectors, and engine control units for automotive and powersports applications. The TB0300 is manufactured to meet original equipment fit, form, and function requirements.

Key Features:

• OEM-quality construction engineered to meet original equipment specifications
• Throttle plate (butterfly valve) precisely regulates airflow into the intake manifold
• Integrates with the vehicle's ECU for accurate fuel delivery and engine management
• Direct-fit replacement designed to restore proper throttle response and idle quality
• Manufactured by Magneti Marelli, a trusted global OEM supplier of powertrain components

A worn or faulty throttle body can cause symptoms such as rough idle, poor acceleration, hesitation, or an illuminated check engine light. Replacing it with a genuine Magneti Marelli unit helps restore proper engine performance and drivability.
