This system is made for stock MAF (Mass Air Flow Sensor) calibration. Meaning this system works perfect with no check engine lights, no matter if your truck is stock, or highly modified. 

Has a bolt in heat shield that is vary well sealed to keep underhood temps away from the large Filter, it provides a fresh cold air supply straight to the filter for lower egt's and better performance. It is normal to see 150-250 deg drop in egt's with this system.

We use only the best filters on all our intake systems
