OK im not gunna be buyin an intake atleast till end of school june and was wonderin if i get just a drop in K&N if itll do anything because i have Apex'i N1 exhuast on my car and i can feel that my car is pushin out more than it is taken in will the filter help out on this, and also i figure that if u have full exhuast like i do with no intake u get worse gas mileage, this is just my intuition but is it right ot wrong?

 

short ram is good for lower rpm
intake system is good for higher rpm
CAI (cold air intake) is the best u can do

partially way out..? u catch the K&N inlet filter redesign the air intake from the airbox to the outlet (bigger and maybe up to the front),better leave the box in or ull lost performence
