changes some aspects of air coming into your engine like velocity, and turbulance and other things like increasing your plenum volume. Usually the changes are slight, but it can help with fuel atomization which can increase power, and it will change your powerband slightly. They are used for fine-tuning an already well tuned engine, which an l03 is not. But neverless, they have been used, and do improve performance. I would guess about as much as "power pulleys."

and remember, all engines/cars are different, even if we call them the same names. only way to know for sure if its good for you or not is to try it. Then you should tell everybody what you think.

 

Sounds like you have enough mods to make a difference. Your throttle response should be a little better and you should have a little more torque. Not much but every little bit helps. I put mine on with an open air element. I think most of my power increase was do to the element but I am sure the spacr helped to
