I have an 02 Chev Z71 4x4 and I was wondering what there is for positive power adders. I currently have the computer reprogrammed for more power,a K&N drop in replacement filter, and some Bosch 4+ plugs. I was wondering if anybody has replaced the mass air flow sensor, thethrottle body or added a spacer, etc. Im just looking for bolt on power adders Idont want to be teearing into the motor andchanging cams or anythinglike that.

 

A COLD AIR INTAKE, A FLOWMASTER SUPER 40 MUFFLER OR CAT-BACK SYSTEM, A SET OF HEADERS AND A GRANATELLI MASS AIR SENSOR WOULD DEFINITLY WAKE UP YOUR RIDE. I HAVE A 03 AND ADDED THESE PLUS SOME OTHER GOODIES. YOU WILL BE HAPPY WITH THE EXTRA POWER. HOPE THIS HELPED
