Edelbrock AVS2 650 Calibration Kit for 1905 & 1906 Throttle Bodies — precision metering parts & sealing hardware

The Edelbrock Calibration Kit AVS2 650 Series 1905 & 1906 is a precision set of tuning components designed to calibrate and optimize Edelbrock AVS2 650 throttle bodies for reliable airflow and fuel metering.

This calibration kit contains the specific parts needed to fine-tune Edelbrock AVS2 650 Series throttle bodies (part numbers 1905 & 1906). It’s engineered to work with the AVS2 platform so you can adjust metering characteristics and restore correct performance after modifications, maintenance, or upgrades. Every kit reflects Edelbrock’s development and quality control practices so technicians and home mechanics receive parts that match the original design intent.

What components are included and why do they matter?

The kit supplies the calibrated hardware required to set throttle body metering and airflow precisely. These components replace or adjust key internal parts to bring the unit back to spec or to adapt it for different setups.

• Precision metering bits sized for AVS2 650 Series 1905 & 1906 bodies
• Sealing and fastening hardware to ensure leak-free reassembly
• Instructions or markings to guide correct placement and orientation

How does this kit improve throttle body performance?

By providing calibrated parts that restore intended metering geometry, the kit helps the throttle body deliver the correct air-fuel ratios across the operating range. That consistency aids engine management systems in maintaining smoother throttle response and more predictable operation.

• Restores original metering tolerances after wear or modification
• Reduces variability between throttle openings for repeatable performance
• Helps avoid common drivability issues tied to improper metering

Will this fit my vehicle and how do I install it?

The Calibration Kit is intended specifically for Edelbrock AVS2 650 Series throttle bodies with part numbers 1905 and 1906. Installation typically requires basic mechanical tools and familiarity with throttle-body disassembly; follow Edelbrock’s instructions or have a qualified technician perform the work.

• Fitment: AVS2 650 Series 1905 & 1906 only
• Installation: moderate skill level, clean workspace recommended
• Reassembly: torque and sealing details required for correct operation

When should I replace or recalibrate using this kit?

Consider the kit whenever you notice inconsistent throttle response, after routine maintenance that disturbed internal parts, or when changing supporting hardware that affects airflow. It’s also appropriate any time you remove the throttle body for inspection, repair, or upgrades.

• After wear or visible damage to metering parts
• Following throttle-body service or cleaning procedures
• When adjusting setup for modified intake or engine changes

Who is this for: The Edelbrock Calibration Kit AVS2 650 Series 1905 & 1906 is aimed at performance enthusiasts, professional tuners, and DIY mechanics who own AVS2 650 throttle bodies and need factory-matched replacement parts to restore or refine metering. If you maintain, upgrade, or tune Edelbrock throttle bodies, this kit provides the calibrated hardware required to keep the AVS2 650 operating within design parameters.
