Do TB spacers work? Are they worth the money and time? Also, if anyone has a TB spacer and a CAI installed, where there any issues with the CAI tubes lining up?

Ive always had good results with TB s on my other vehicles never installed one on my truck but their is quicker throttle response you can feel when you have one on.

TB spacer = waste of $$ unless you intend to drill it and put nitrous jets in it.

The idea behind a throttle body spacer is to mimic a carb spacer. On a carbed engine the spacer gives the air and fuel more time to mix together. Since a fuel injected engine injects the fuel far after the throttle body it literally does nothing for you.... Just creates a longer path for the air to travel. As HemiLonestart said the only reason to use one would be to run nitrous.

In some cases the spacer is actually narrower than the TB opening. Also some manufacturers design their CAI's so that you have to use the spacer to bolt it on properly.

I would suggest porting out your current throttle body and narrow down the webbing before thinking about a spacer on the Magnum engine. Proven gains doing that.

TB Spacer and CAI on 5.2L Magnum

I have a 1998 Ram 1500 with the 318. I have a spectre cold air intake and throttle body spacer. I didn't plan on to much of a difference, but i did notice the quicker throttle response. I did have a problem stuffing the intake on after putting the spacer in, but that's nothing a hammer couldn't fix.
