I havent seen one made specifically for the 5.3 but any 6.0 is supposed to work. IEATSRT8.com even lists there Trailblazer SS CAI to fit the 6.0 and
5.3. I have decided that I will be buying the IEATSRT8 kit as soon as funds allow (every spare penny is getting pumped into the Camaro right now). Keep us posted on what you decide on.:thumbsup:
