Yes with a factory intake you will defintely see a seat of the pants difference, just make sure you trim the rubber flap out of the way at the top. I drilled a series of small holes very close to each other in order to keep debri out. I also suggest is getting rid of the highly restrictive muffler, it necks down a 3.5" exhaust to 2.5" and then throws it through an offset muffler. Backpressure is good on a gasser not a diesel!! Just go straight pipe, or like I did with the Walker BTM muffler, my EGT's dropped 100-150 degrees between the AIS/Zoodad/BTM combo, more air in means more air needs to get out!!!
