Use this throttle body assembly when replacing a worn or malfunctioning unit on compatible Nissan vehicles. The TB1152 is engineered, developed, and tested to meet OE requirements, with performance targeted to match or exceed the original equipment it replaces.

Key Features

• Electronic throttle body assembly for fuel injection systems
• OE requirement-focused engineering and validation
• Direct-fit replacement for select Nissan applications
• Built to deliver consistent throttle response and airflow control
• Spectra Premium replacement part number TB1152

Detailed Description

Spectra Premium TB1152 is a fuel injection throttle body assembly for vehicles equipped with electronic throttle control. It is intended for fitment across multiple Nissan platforms, including 2021-2023 Frontier, 2014-2023 NP300, 2014-2023 NV350 Urvan, 2014-2022 X-Trail, 2016-2020 NP300 Frontier, 2014-2020 Rogue, and 2013-2018 Altima. This part number, TB1152, is a practical OE-style replacement when the original throttle body no longer maintains proper airflow or throttle signal response.

This part cross-references Standard Ignition (e.g., S20183) for the same application.

What It Is Used For

• Restoring throttle response after electronic throttle body wear
• Correcting unstable idle caused by throttle body contamination or failure
• Replacing a unit with inconsistent airflow control
• Addressing drivability issues tied to throttle signal irregularities
• Returning fuel injection system operation to OE-style performance

Installation Notes and Tips

Verify the vehicle year, model, and engine application against the fitment list before ordering. After installation, follow the manufacturer’s relearn or calibration procedure if required by the vehicle system. Confirm connector condition and intake tract cleanliness during replacement to help avoid repeat faults.

Quality Assurance

Spectra Premium states that its electronic throttle bodies are engineered, developed, and rigorously tested to meet OE requirements, and that this assembly meets or exceeds the performance of the original equipment it replaces.
