Holley EFI Billet LS Throttle Body Cable Driven with Low RPM Taper

The Holley EFI Billet LS Throttle Body is a cable-driven LS throttle body (also called an EFI throttle body or air valve) for LS-based engines. It is machined from billet aluminum and has a low RPM taper. Holley designed it for stock LS engines and for turbocharged, supercharged and big-cam builds that need more airflow.

Key Features:

• Premium billet aluminum body: CNC-machined for a high-tolerance fit and finish.
• Low RPM taper: The tapered transition is designed to eliminate low-RPM drivability problems.
• Oversized bore: Larger than many other LS throttle bodies, for more airflow.
• TPS clocker: Lets you rotate the throttle position sensor back into the ECU's required idle voltage range. This helps modified engines avoid TPS voltage problems.
• Idle bleed adjustment: Lets you adjust idle without changing throttle position or TPS voltage at idle.
• PCV passage valve: Closes for forced induction applications, so you don't need to plug the PCV port.
• Black anodized finish: Protects against corrosion and gives a modern look.
• Cruise control provision: A built-in provision accepts a cruise control cable.
• Cable-driven design: Works with a traditional throttle cable setup.

Holley EFI's billet LS throttle bodies are meant to simplify installation and tuning while delivering better throttle response and airflow. Choose the bore size that matches your intake manifold and power goals.
