Airaid PowerAid Throttle Body Spacer for Select 1997-2004 Ford & Lincoln (5.4L) - 400-591
$157.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1997-2004 Ford F-150, F-150 Heritage, Expedition, and 1998-1999 Lincoln Navigator (5.4L).
The Airaid PowerAid Throttle Body Spacer is engineered to increase off-idle torque and mid-range performance between 800 and 3,000 RPM. This spacer utilizes a patented Helix Bore design to spin the incoming air charge as it passes through the throttle body. The resulting air velocity improves the atomization of the air/fuel mixture as it enters the combustion chamber, leading to enhanced part-throttle torque and sharper throttle response.
Designed as a straightforward performance add-on, the PowerAid spacer is a true bolt-on upgrade that can be installed in under an hour with common hand tools. The kit requires no drilling, cutting, or permanent modifications to your vehicle's factory intake system, making it an efficient solution for improving towing and daily driving power.
- Patented Helix Bore design for increased air charge velocity
- Enhances off-idle torque from 800 RPM to 3,000 RPM
- Improves mid-range power and air/fuel atomization
- Simple bolt-on installation with no drilling or cutting required
- Manufacturer Part Number: 400-591
