buschur is running a lotta airflow and also a stand alone that does away with the maf. so there's no downside for him to run a cone and pipe... whereas some will debate that there will be weirdnesses that need to be accounted for or are best left unweirded by staying with the stock air box. no one will dispute taht br made more power with an intake, but until you run aem they will recommend you stay with stock air box.

 

I have the injen intake and upper pipes with an HKS SSQV and I have no problems. I am getting it tuned soon, however, there is no knocking, no idle problems, the turbo spools sooner, starts at about 2K, louder, and holds to 20psi now, un like previously, when it only spiked to 20 and dropped to 17-18psi. However, I do have it recirced, for I didn't want her stalling out at idle.
