Bolt on horsepower! The PowerAid Throttle Body Spacer from Airaid is designed to greatly improve the low-end torque and horsepower characteristics of your engine. PowerAid accomplishes this by spacing the throttle body 1" and adding a dyno-proven, Helix-style bore. As the intake air passes through the spacer, the Helix bore creates a vortex action that improves atomization, creating a more complete combustion and an efficiently burning engine. The results are improved driveability and increased fuel efficiency.

  • Improve low-end torque and horsepower
  • Improved driveability
  • Increased fuel efficiency
  • Improves atomization, which means more complete combustion

Increase the horsepower and low-end torque of your Chrysler 300 while increasing your fuel efficiency. The PowerAid spacer is legal in all 50 states, will not void your new car warranty, and can be used with any grade of fuel.

Noticeable change
A noticeable improvement in power and responsiveness, from the ground up. Adds about 0.6-1.0 litres per hundred to fuel consumption but with the cold air intake that puts you back about to where it started as a standard build from the factory. Most pronounced effect is at initial take off and from 100kph to about 140kph, where torque increase is very significant. The device took about 10 minutes to fit and two socket drives (one for the smaller old bolt-heads). Piece of cake.

Poweraid throttle body spacer
This is a great product. It's super easy to install, I think in total it took me under 10 mins to install. Autotrucktoys always ships quickly and accurately and I really like buying from/through them. I hope this will help a little in gas mileage I already feel a little difference in HP and torque.

Throttle body spacer
Quality parts. Easy to install. Cant really tell if it improves anything. Dont over tighten the throttle body screws!!
PowerAid Throttle Body Spacer
I've only had the product installed a few days. I'm still waiting to hear the whistle to let me know it's working. I have noticed an increase in acceleration, more on mid range and top end, and the pedal response is better. My vehicle only has a modification to the ignition system coil wires and plugs. I am in the process of evaluating exhaust systems. I want one that's effective and quiet.

Throttle body spacer
I was skeptical at first that this product would do all it claimed. Well....it took me about 15 minutes to install. The throttle body spacer used in conjunction with a spectre cold air intake were great! Better throttle response. ..a few more horses...and a little more torque. I'll post mpg results later. The product was well worth the money!

Better drivability
I had this part waiting on my workbench for about a year or more. I got it with some other parts and wound up feeling it couldn't possibly make much difference. I had already put on a K&N intake and a low-restriction Magnaflow exhaust on and was very pleased with those changes: better mpg much more power important living at 7000 feet. Putting the throttle body space on literally took about 10 minutes. It bolted right up and fit well. Having it on a few months it has improved mid-range acceleration. I regularly get 27-29 mpg on town and mid-high 30s on the highway my PT is a manual. The car just feels much more responsive-especially on the highway. The whistle? Perhaps an unfortunate gimmick but a small price to pay for what the part does plus it looks cool with my chrome intake manifold. A nice perk as my painted vanity cover no longer fits.

Like It So Far
So far I like the product. I have a K&N cold air intake and now to add this. The whistle is noticeable but I do feel like my throttle response has improved. The fuel mileage will tell soon enough. Power gains not sure of either if only throttle response improves I will take it. Would recommend this product.
