My 2006 Chevy Suburban has a K&N cold air intake and a computer chip installed,when I add the throttle body spacer on the open rosd running at a steady 70 mile an hour I gained about.8 miles to the gallon. Not much considering the cost of the spacer. And driving around town I lost about 1.7 mile per gallon - terrible investment if you ask me ,and no low end improvement what so ever
One Trick Tube!

Very easy install on my 4.8 V8. Only took 15 minutes. 2 mpg increase with a bit more power too. It has a Muscle car roar to it when you step on it. I also noticed that the transmission didn't need to downshift as often. Definatly a great buy and a must for any gearhead!
