Sorry all my pics are rotated for some reason. In the end, the air temp with this mod was a little lower than the stock airbox (about 10 degrees) but the temp at the area where the stillen gen 3's take in air was always better. I am convinced that its not just a cooler air charge but the resonance of the length of the stillens coupled with a smoother airflow at the MAF that probably accounts for their magic.
