Airaid Holley 4150/4160 Series/ Edelbrock Sq. Flange/ OE Sq. Flange - 100-701

The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes its unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power. This product is legal for sale or use in all 50 states only for 1989 or older vehicles equipped with a 4 BBL Holley carburetor (CARB D-609).

Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

We started with air filters, but our vision has grown broader. Pushing beyond the street, into new rugged frontiers, we are optimizing air intake across the entire spectrum of internal combustion. From powdery snow-slopes, sand dunes, mud bogs, drag strips and road trips; to finish lines everywhere, across every terrain, we power drivers and explorers to dream bigger, adventure further, and discover their full potential.
