I need help. I have a 97 CHEVY K1500 Z71 with a 5.7L 350. I am looking for something to add some power, torque, and maybe help with fuel economy. I was told throttle body spacers are a good, quick, and fairly cheap solution. I was wondering if you guys had any idea if they actually worked, and which one i should go with? I have a couple links of the ones in the price range I'm looking at, for i don't have much money.
