a throttle body spacer only work on a carburated engine. on a fuel injected engine like our 3.8 it serves no benefit. on a carb'd engine the spacer gives the air and fuel extra time to mix, providing a better combustion.
On a fuel injected engine like ours, a spacer does nothing to increase that mixture. our engines mix the air and fuel right in the cylinder head.

I mean you have it now so sure install it, but the vendor claims are highly innacurate.

I'd return the spacer but keep the CAI. It won't give you much, if any performance gain. Ok...no gain, BUT your JK will start to sound better. I have that model as well and matched it with a Flowmaster exhaust. I would not go back to stock for any amount of money.
