i researched on the web and discovered that this is not a new technology. it is mainly used on v8s and v6s. the Helix throttle body bore manufacturer claims that it can increase horsepower and fuel economy. is this possible to do on a 99 prelude or is it just unrealistic?

 

It's poo-poo on a fuel injected engine. They only work on carburetors...

 

TB spacers=waste of $$$ on our engines.

 

pointless
