Airaid300-631-1 PowerAid Throttle Body Spacer

The media could not be loaded.  Definitely increased the low-end throttle response. There is a noticeable addition of torque throughout the low- and mid-range of the throttle position, which means the throttle response throughout this range was also improved. The hesitation has been reduced, and I don't find myself wanting to drive it in to the high-end (above 4k RPM) to get the response I'm looking for. Since the engine now has a better throttle response in the lower range, I expect it will most likely help increase MPG. There was a noticeable decrease in the "droning" as well (when "ECO mode" kicks in).The package says "the whistle tells you its working". The "whistle" is at best unremarkable. I noticed a faint whistle around 2700 - 3100 RPM -- within this range is the only time I can actually hear it whistle. Regardless, I can tell by the engine response that it's working, and honestly, I'm happy it doesn't whistle (noticeably) while it works.--Installation Notes--The instructions are straightforward with the exception of two items:1) you will need an 8mm socket for the TBI bolts -- not a 10mm as sited in the instructions;2) you really should trim your engine cover for a good fit. The engine cover will snap into the ball sockets without trimming it, but it rests snuggly on top of the actuator of the TBI creating an "interference fit". I used a Dremel tool to trim 3/8 inches from the cover around the actuator and it removed the interference (see pictures).

My gosh damn Ram 1500 roars like a fricken dragon version of Beyonce. It might as well be a spaceship now. Thank you Airraid

Installation was very straight forward except the supplied bolt lengths. I installed in my 2019 ram rebel but the kit showed for earlier models in the installation pack... everything fit and holds just fine. I have already noticed the increased fuel economy... especially on highway driving... and lower end torque and throttle response... definately recommend this product

Adds a nice sound when combined with an intake and around the powerband creates a lovely whistling sound reminds me of my wrx when the turbo would aspirate.

I've tried these before on other vehicles I've owned only to end in disappointment. Never added power, fuel mileage, anything. However, I had some money to waste after VW paid me to buy back my TDi so I decided to try and get some better MPG into my Ram 1500 HEMI. I thought, eh why not give it another shot. If it doesn't work, I can get my money back. I already had a K&N intake, Cherry Bomb muffler, and removed some vacuum lines and added a crank case breather. I actually noticed a difference with this spacer. I didn't notice any power, except when climbing hills. It would no longer gear down on the hills that it normally would do so. It also cleaned up some of the stutter on acceleration. It actually did add some MPG also. I didn't notice any whistle that others have noticed until I bought a tuner from SuperChips. (I've also been disappointed by tuners in the past but since the spacer surprised me I thought I would give one a shot. I am happy with it.) Now it will whistle on some hills and at some RPM ranges but it isn't constant and you can't hear it at all if the radio is on. Overall, I am very happy and for me and the way I drive, this was no waste of money.

I was excited to add this to my Hemi, hoping to really wake it up. But I was disappointed, again.... no noticeable difference in power or mileage. I suggest you save your money.

First off, this is not meant to help you gain power. I see several reviews of people complaining about no power gains. Second, if you are getting a whistling noise, you probably didn't install this properly. Lastly, if you don't see mpg gains, you are probably driving with a lead foot. My tests were done under normal in-town and highway conditions while mostly following speed limits. I saw 2 mpg gains within 900 miles of driving.The bottom right hand of the photos show the Avg MPG. Before I installed this spacer, I was getting 18.1 mpg. After installing the spacer, I am currently getting 18.7. So far, I have driven around 400 miles with the spacer installed. I will update when I drive around 1000 miles. So far, I am happy with the purchase. Every bit of gas saved is money earned.*Update* Since installing the spacer, I have driven a little over 900 miles and I am averaging 2 miles per gallon more. That is a huge gain in a Ram 1500 5.7 liter V8.

Well first off it’s not red and I’m pretty sure the inside should not be banged up like this, I know a throttle body spacer helped my other truck so I wanted to try it on the new truck, but it don’t match the red theme I have going on which is fine but the dings on all edges of this is crazy the point is to make the air funnel/tornado but how when is all banged up

Love the look and love the extra power under my feet

It’s amazing came with the perfect screws doesnt whistle loud but does whistle which I love hearing

Great lower end power.

The product arrived as advertised. Very happy with it. I've yet to install it but it did not come with a set of instructions.

Très bon produit
