i have a 1998 tahoe 4 door with 65000 miles. i want to get a throttle body spacer. do you all think it will hurt or help my engine out. oh i also have duel glass pack exhaust.

it will help. the spacer is designed to give the fuel and air a little more space to burn more efficiently. if you have a spacer and throw on a good cold air intake you'll get some nice power.
