Airaid 11-14 Ford Mustang / 11-13 F-150 5.0L V8 PowerAid TB Spacer (Part #450-638)
More Low-End Torque Without A Tune
You have a 5.0L Coyote in your Mustang or F-150. Great engine. But the throttle response below 3,000 RPM is a little lazy. You step on it and wait. The motor does not wake up until you rev it out.This is the Airaid PowerAid Throttle Body Spacer. Part #450-638. Fits 2011-2014 Ford Mustang GT and 2011-2013 F-150 5.0L V8 engines .Airaid has been making performance parts since 1997 . This spacer is designed to enhance off-idle torque from 800 RPM to approximately 3,000 RPM . It uses a patented Helix Bore design to spin the incoming air charge as it passes through . The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture . The end result is more part-throttle torque and improved mid-range power .The "Coyote Whistle" Fix
If you own a 5.0L F-150, you know the whistle. A high-pitched intake noise under light acceleration. It is annoying. Airaid designed this spacer specifically to eliminate that whistle . Install it backwards per the instructions, and the noise is gone . That alone makes it worth the money for a lot of owners.What You Get
