The PowerAid Throttle Body Spacers from Airaid Premium Filter Company are designed to greatly improve the low-end torque and horsepower characteristics of your engine. PowerAid accomplishes this by spacing the throttle body one inch and adding a dyno-proven Helix style bore(s). As the intake air passes through the spacer, the Helix bore creates a vortex action that improves atomization creating a more complete combustion and an efficiently burning engine. The results are improved drivability and increased fuel efficiency. The PowerAid spacer is 50 state legal, will not void your new car warranty, and can be used with any grade fuel. The 400-531 fits the 2006-2008 Lincoln Mark LT 5.4L, 2005-2006 Ford Expedition 5.4L and 2004-2008 "New Body Style" F-150/250/350 5.4L 24V Triton engines. Note: This Poweraid will not fit "Heritage" trucks and cannot be used with a 400-140 Airaid. It can be used with a 400-140-1 Airaid.
