right, but what about the question regarding use of the stock cover? is it just as "restrictive" weather i use the inlet tubes, which are rather small in regards to where the air comes from, or if i use K&N cone filters. any ideas as to where or what i could do in regards to the shields? w/o having to go out and paying for something custom made in regards to some "bent metal". i am trying to find an easy, and relatively cheap way to make a custom intake with the stock cover, but most important EFFECTIVE performance wise.
