Using S&B's largest filter yet will increase your truck's power and give you a nice underhood growl. The kit includes a larger pipe than OEM to funnel the air toward your engine! 
The OEM intake tube is small in diameter and highly restrictive. S&B's intake tube was designed with a huge diameter to allow for insane amounts of airflow to be fed to your engine. More airflow equals better performance. We use an innovative insert in order to get our gigantic tube to work with the MAF sensor parameters of a stock truck.
