    MOST people here will tell you to save you $$$ and not get one. I have an airaid TB spacer myself and love it. From my experience there is a definitely noticeable improvement in the low end and it definitely helps in my mpg. I have run a number of tanks with and without and my mpg is about 8-10% better with the TB spacer on. I'm not really in the upper RPM range very often so I can't comment on how it affect that but I will put my hat in the ring and say that I am a fan of mine. I have also noticed that my mds kicks in at a lower speed and stays on longer...most likely why I get the better mpg.

    Now...not to step on any toes but I believe fireman will be chiming in here soon telling you to save your $$$. As he is pretty much the reigning king of magnums here I would NEVER suggest you not listen to him.

    Honestly you'll be good with or without...it all depends on what you are looking to get out of it.

    The only magic a throttle body spacer does is remove money from your wallet. The original use was for carbureted setups in drag racing to increase the velocity of air flow past the venturies for the air and fuel mixture. Otherwise they do nothing, zero nadda on a fuel injected system. This is a well known and proven fact. I just wanted to put that out there, what you want to spend your money on is your choice and if you enjoy it the n that's all that really matters...

    Some engines they work well on, others, not as good. On some there could be adverse effects. On throttle body injected or carbureted engines, spacers increase the overall manifold volume and create a tumbling of the air, allowing for better atomization of the fuel. Since the Hemis are multi port injected, and each cylinder has it's own injector, adding to the plenum volume and increasing the tumbling of the air prior to the addition of fuel, has little or no effect at all.

    You can probably accomplish better performance by just keeping your fuel injectors clean!

    I have one sitting in a box I'll sell you for $25 + shipping if you want it? I originally bought it for $75, used it for a week and then bought a CAI that it did not fit with. I'll take pictures if you want, just let me know.

    I find it interesting that someone has noted better MPG with one. Maybe the specifics of that motor are just a bit different? Just like there are some factory freak motors that can't be denied.

    Back when my motor was stock, I gained .5 MPG with a 180 thermostat on a repeatable trip I take frequently.
