Edelbrock AVS2 Carburetor 500 CFM w/ Electric Choke - Chrome Plasma

This Edelbrock AVS2 carburetor, part number 1901-CP, comes finished in a striking Chrome Plasma coating and features a 500 CFM rating with an electric choke. It's built for street use and incorporates annular flow booster technology, designed to give you drivability that feels close to electronic fuel injection the moment you press the accelerator. The key to this improved response is the annular ring, which replaces the typical single brass tube with eight evenly spaced openings. This design sprays fuel evenly into the airflow, smoothing out acceleration and eliminating flat spots, especially in the low to mid-RPM range, without compromising top-end power.

The Chrome Plasma finish is applied through a meticulous 7-stage process, ensuring a durable and brilliant look that stands up to engine bay conditions. This AVS2 carburetor is also built tough; it's unaffected by engine backfires because it doesn't have power valves that can blow out. Tuning is made straightforward with metering rods and springs that can be swapped in seconds without needing to remove the carburetor or drain the fuel. Edelbrock's AVS2 carburetors are known for holding their tune, meaning your adjustments stay put and performance remains consistent over time. The updated primary and secondary booster clusters are calibrated for today's fuels and octane levels, and the unique Qwik-Tune secondary air valve allows for extensive calibration of the secondary circuit using simple hand tools, letting you tailor it precisely to your application.

The two-piece design of the AVS2 makes tuning and maintenance easy. You can adjust the float level or replace internal components without draining the carburetor or removing it from the engine. This particular 500 CFM model, the 1901-CP, is manufactured by Edelbrock in the USA.
