I just received and installed swift intake that I got from (club lexus classified!) to my stock gs 4. Imressive power increase and killer sound. Thanks everyone.

 

Hey Bad ...

if you combine that with a professionally installed torque converter (I believe Swift sells the Dragon version) you will REALLY be loving life !!! Mo installed both the intake and TC on mine and my car hauls a$$ .... but that doesn't mean I don't still want a supercharger or Turbo ..
