I installed this intake in about 45 minutes start to finish in my driveway. I already have a 4" Turbo back straight pipe from mbrp so with the addition of this intake it really made the engine come alive. More power more tourqe and a loud whistle under the hood that I love. Easy to install and came with the free air cleaner kit. I love it thanks XDP.

Just installed the AFE Stage 2si Intake on my 2004 F-350 6.0 and wow! Really made the turbo sound louder and brought the whistle out from hiding. I decided to go with the SI intake from afe b/c I didn't want all the cab noise but I still wanted the power of the Stage 2. Great Product!
