🚀 Airaid PowerAid Throttle Body Spacer (400-591) - Enhance Your Vehicle's Performance and Turbocharge its Throttle Response Review

easy installation, don't see any pluses. but now he's there, whistling with a sharp acceleration. pretty cool in that sense

Do you want to whistle in traffic?! This is the spacer for you! Simplified installation instructions, fits perfectly with the BBK 75mm throttle body and convinces! The truck drives like it has something to prove.

Has a noticeable difference in throttle response and appears to have less horsepower. Had to make some adjustments to adjust the throttle cable, the picture in the manual was for a different intake than the one on mine, but no complaints overall.

Bought for my 1997 Ford Expedition 5.4 liter engine and overall not impressed. No noticeable difference in acceleration (even at low torque). Makes a half hiss/hiss at 1/4 throttle, which sounds cool. Paired this with a cold K&N air intake and it was a pain in the rear to align later. After moving everything too far forward I had to remove the K&N entirely and make some adjustments so it doesn't rub on the fan shroud and match the metal box and rattle (which it still does since it's at an odd…

Honest. It probably won't do much. It makes a cool turbo whistle that you hear through the air intake. Volume and pitch are controlled with the right foot. No noticeable noise during WOT. I like it but some people hate it. In terms of performance, I don't see how this could work given the complicated design of new car air intakes (sharp turns and bends), let alone expelling only a small amount of air when the throttle isn't fully open. goes through those ridges on the top and bottom of your…
