The Insta-Spool Entry Level Intake is a design that deletes the factory, extremely restrictive, air box and replaces it with a S&B 5" outlet Super Cone cleanable filter that is far superior to the commonly used BHAF air filter. The filter flows a monstrous amount of air. This is the same filter I use for the all aluminum intake kits. The factory air filter box is good for just that, a factory stock application with no power adders. As an engines power output is increased it's demand for more air increases with it. The kit comes with all of the hardware, a mounting bracket/ filter support, and an adapter boot to go from the filters 5" outlet to the 4.5" factory intake elbow inlet. By allowing the turbocharger to have sufficient airflow and a lower atmospheric pressure drop through the filter the intake charge temperature is lower and incoming air more dense. More dense air will make more power causing quicker spool up and lower exhaust temperatures.
please send me a email if interested in one of these as i currently make them when ordered so i can custom build them to your specifications.
