1/2 inch spacer

[Tony2000]

has anybody done this to the L's, I read on F150online about someone making this 1/2 inch spacer to fit between the supercharger and the upper intake. Does this really work soposed to give you 30cfm more of air flow.

I have seen these sort of things before on other cars, basically a spacer between the throttle body and the intake.

Here's AirRaids info on them :

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.

I had one on my Jeep....it actually did help out on the low end a little bit...also made a cool ass sound. It ended up leaking air at some point and sending a SES light so I removed it.

Would it help on a Lightning...who knows...but they are pretty cheap.
