The #164596 is only an ok CAI.
This CAI is only an ok intake. The screw holes in the aluminum lid didn't allign correctly to the mounting in the intake box. The two mounting bolts for the intake box were too short and wouldn't fasten the intake box to my truck.I had to go buy two longer ones so that I could properly fasten it in. Volant did however help with acquiring a new lid for the box. Unsure if I would purchase another and recommend this CAI to anyone else.
