Airaid PowerAid Throttle Body Spacer AIR200-550 for 1991-1995 GM 7.4L 454 TBI

The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it's 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. The POWERAID Throttle Body Spacer is designed to enhance mid-range torque using a patented Helix Bore which spins intake air going through the throttle body spacer. Mounting hardware included for installation.

• True bolt-on upgrade that installs in under an hour with common hand tools. No drilling, cutting, or modifications required, making it one of the easiest performance add-ons you can install.
• Provides Stronger Mid-Range Power

The Airaid PowerAid Throttle Body Spacer is engineered to improve off-idle and mid-range torque on compatible General Motors 7.4L 454 TBI applications. Its patented Helix Bore design creates a spinning air charge as intake air passes through the spacer. This increased air movement helps improve air and fuel atomization as the mixture enters the combustion chamber, supporting stronger part-throttle response and improved mid-range power.

This Airaid AIR200-550 throttle body spacer is a true bolt-on performance upgrade designed for straightforward installation with common hand tools. No drilling, cutting, or permanent vehicle modifications are required, and mounting hardware is included. The spacer is intended to enhance usable torque from approximately 800 rpm through 3,000 rpm while maintaining a practical installation process for street-driven trucks and SUVs. It is EPA compliant and carries California Air Resources Board Executive Order D-609.
