GM LS1 to LS2 Throttle Body Harness Adapter

• Throttle-body airflow design supports dependable throttle response and properly matched EFI airflow characteristics.

• Cast/billet elbow construction with black finish helps position the throttle body while maintaining clean engine-bay fitment.

• Vacuum port and MAP sensor port provisions should be planned around sensor routing and accessory clearance.

• Commonly used in Chevrolet Silverado, GMC Sierra, and Chevrolet Camaro LS applications; verify intake and ECU compatibility before installation.

Designed for GM LS1/LS2/LS6 applications, this throttle body elbow helps adapt EFI throttle body placement to 4150-style intake layouts while supporting clean airflow routing.

Throttle Body Adapter Fitment
These dimensions should be checked against hood clearance and throttle body placement.

Elbow Construction & Layout
Durable construction with a black finish The elbow helps create a clean transition between intake manifold and throttle body.

Sensor / Port Provisions
Plan sensor placement, vacuum routing, and accessory clearance before installation.

Installation & Clearance Matching
Common use cases include Chevrolet Camaro, Pontiac Firebird, Chevrolet Corvette. Verify throttle body size, 4150 flange compatibility, cable bracket needs, and hood clearance before final assembly.
