I have a throttle body spacer for sale.I ran it on my parent's avalanche and my dad was not happy with it. So I am willing to part with it with all hardware and instructions in the original box for $50. This will include the shipping and handling.

 

What was he not happy with?

 

He said that it did not increase the MPG as he hoped it would. He was comparing it with the one on his 92 chevy.
