Airaid PowerAid Throttle Body Spacer AIR510-502 for 1995–2002 Toyota Tacoma and 4Runner 3.4L

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, part number AIR510-502, is designed to improve off-idle and mid-range engine performance on select Toyota Tacoma and 4Runner models equipped with the 3.4L engine. Its patented Helix Bore design spins the incoming air charge as it passes through the throttle body spacer, increasing air velocity and supporting improved air/fuel mixture atomization as the charge enters the combustion chamber. The result is stronger part-throttle torque from approximately 800 to 3,000 rpm and improved mid-range power.

This Airaid PowerAid spacer is a true bolt-on performance upgrade that installs in under an hour using common hand tools. No drilling, cutting, or permanent modifications are required. Mounting hardware is included for a straightforward installation. The part is EPA compliant and carries California Air Resources Board Executive Order D-609. Professional installation is recommended, and vehicle-specific fitment should be confirmed before ordering.
