I ordered a C&L Inlet Pipe ( cause I like the way It looks) anyway ,I had some questions ,and there happen to be one of the engineering group personel close by . So I bombarded him with questions.. and after every thing was said and done.. He told me that during there Dyno tests ,they had 6 different stangs ,all modified differently ,and stock to . and with all there tests they found out that with the stock airbox - the restrictor , with a K/N ,made more H/P on all stangs then any other combo (including the conical cone) But something else they learned !!!!
By deleting the MassAir bracket that secures the MassAir to the fender ,they were making even more H/P . It's like this in between the airbox and massair you have what they call .. the bellows . ( that is the section of tube between airbox and Massair) what happens under torque,is the motor lifts and changes the angle of airflow at the bellows. By disconnect the bracket that secures the Massair ( i should say deleting it) the whole intake tract moves up and down with the engine torque. thus promoting cleaner air and more H/P hope this made sense
