my srt has a needwings single intake and still the kn small filter,I replace it with a filter about twice the size and lenght,car really feels faster or could it just be me,oh the car has a code 3 pulley needswing ported enlarged stock manifolds and a exhaust,if i keep this filter I will have to purchase a billet grill just need some opinions on this matter

 

Mine's an N/A with a single NW CAI, I also put on a larger K&N, it fits fine behind the stock grille :

 

ok thats great didnt want to hinder my performance
