I have a 98 A4 1.8T AWD, I just put in a chip and a stock S4 exhaust. What kind of K&N cold air intake would I benefit from the most?

 

i heard the cone type k&n give you a nice sound, a little more throttle response and what not. you can also get the drop in replacement which is overall not as thick as the original one which helps your engine breath easier = better response, mpg and whatnot
