I WOULD REALLY LIKE TO HEAR some more folks' experiences. I know most leave the 3.0 stock, but for as many that have sold there has to be a very significant Tuning Community? Maybe I'll just do the K & N drop in?? I've had pretty good results from CAIs and SRIs from K&N, JLT, CPE and COBB on previous Mustangs and Mazdas. Please Advise - Thank You.
