I have one of these a friend gave me for my 07 F150 Harley Davidson and I'd like to hear from anyone here that has tried it out. I'm not so sure about the reviews online about it. It looks like it will restrict the air flow, being that the throat is a bit smaller than the manifold inlet.

Thanks for reading, let me know what you think.

 

The only thing throttle body spacers do is lighten your wallet. I have NEVER seen any definitive proof that they do anything.

 

It's an expensive paper weight and nothing more.

 

Does nothing for fuel injection systems.

 

Thanks for the input everyone. I didn't think it was worth it, and making your intake inlet smaller is not a performance advantage. While putting a little spin on the airflow will improve it.

 

Yeah, but then the air flow is split into 8 flow paths.
