I currently have a black 07 Sierra Z71 5.3L with flowmaster duels and I am looking to mod my current setup to get some more power and tq out of my truck. I have been doing some research while bored at work and this is what i came up with...I want to add a throttle body spacer and a Cold air intake but i dont know which to purchase...I have my eye on these...give me some feed back
  • TB Spacer
  • Intake
Open to any other performance suggestions as well...
Future Mods: 2.5 Leveling Kit, 20% tint, Performance chip
