I'm hoping for something that eliminates the saxophone at a reasonable cost.
Are you referring to the part before or after the airbox?
The part that currently none of the widely available CAI's replace. The restrictive bend that's in the stock intake.
Not sure what you mean by before or after airbox... There really isn't anything after the airbox...
PM Spartn27....
He has currently just fabbed a unique RAM air induction that replaces the whole intake and looks good too
He is doing one for me also... Some new ideas with him.... For mine we will be replacing the piping from the filter box to turbos and a new lid for the filter box to connect them for the filterred air. I am retaining the stock filterbox and the air inlet to it (the one that begins under the plastic front fascia of the engine compartment where the air comes in from outside. He as the option of adding a second intake from the front grill area or the left wheel well inner skin.
Just FYI... most people call the OEM piping from the filter box to the turbos the "saxophone" because it makes a 180 turn and decreases in size.When 4DR and I dyno'd my '13 SHO with the entire OEM intake in place and also with the filter box removed (leaving only the saxophone pipe to the turbos) there was no difference in back to back dynos. So it appears, in the vast majority of cases, that the engine gets all the air it can use via the initial intake from outside and filter. I am excited to replace the filter to turbo piping and test it again.
So I believe that the restriction (if any.. it's still unproven performance-wise) is after the filter. I once thought the small and twisted outside to filter box tubing was a problem... but it appears not to be the case as pointed out above... IMHO Ford engineers did this right.
The CAI's on the market offer eye candy and a change in sound.. usually more turbo spooling sound.... And a lot of folks want that as personal preference... The Airaid and K&N CAIs have been demonstrated on the strip to even cause slower times in several members cars that were fixed by replacing the stock intake on reproducible back to back runs.
