i have to disagree. it does appear to have an aftermarket intake and a short throw shifter. notice they don't get a close up of the pulley. i have always seen the aftermarket pulleys an aluminum color and not black like the factory one. now i could be seeing belt or a black pulley but either way wouldn't you want to get an up close picture of that if it was a selling point.

also even the cars i have seen get the up grade levels their cars would still run fairly normal and idle normal before the tune. you shouldn't get the shuddering or a bouncing idle.
