Throttle body spacer question
Have an 11 JK sport, ordered a afe cold air stage 2 and a throttle body spacer. Have read many mixed reviews on it's effectiveness. Anyone experience any positives, or negatives after installing it?

Throttle body spacers are useless on a fuel injected motor. They served a purpose back in the day when everything was carbed but no more.
They worked by increasing plenum volume which resulted in more top end power on carbed motor. The idea is to produce more efficient atomization of air and fuel. Because with a modern fuel injection engine the fuel is mixed with the air in either the intake runner or directly inside the cylinder. These spacers have no effect.
Save your money.

Because there are a lot of people who are not like you and won't bother to ask the question. They will just purchase the spacer.

There are a number of aftermarket "upgrade" things that are a total waste of money, my fav is the "electronic rust prevention" system that some stores sell. The only way that electric galvanic protection would work is if you planned on parking your vehicle under water...
