5/16 spacers etc? what r they ?

 

basically.....they put more space between engine and plenium....thus allowing more air in at a time....basically like putting your finger on a hose to increase pressure. If theres more someone please add lol...i got a motordyne 1/2 spacer, insane...

 

not really....its more like getting a bigger hose. There's more room for the air to flow at any given time, the pressure of the air does not change.

 

do som research in the tech area and the answer to your question will be found...
