Airaid PowerAid Throttle Body Spacer for 2003–2004 Toyota Tacoma 3.4L, Part Number AIR510-503

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
