Airaid 200-617 PowerAid Throttle Body Spacer

I added this to my 2007 Tahoe, which I had already upgraded with an Airaid 200-196 Cold Air Intake. Installation was simple, though the intructions are not the easiest to understand without comparing to the engine compartment several times (that could just be me, I tend to be very thorough). The combination of CAI and this spacer provide a noticable improvement - I no longer feel like the engine is just bareley making enough power to maintain speed. I rarely notice the additional noise, and even when I do hear it, it is not so bad that I regret installing the spacer. I consider this a worthwhile upgrade, though I am not sure I would do it without the CAI as well.

Installed on a 2008 Tahoe LS 5.3 Flex fuel. This was installed in conjunction with a K&N Cold air intake kit. Total fuel mileage increase 2-3 miles a gallon hwy, 1 MPG city. Throttle response improved. If you can keep your foot out of the throttle i this you will see a small fuel economy improvement. I think it is a worth while investment if you are looking for simple easy to install performance add on. I did not notice ant loud whistling from this application.

Perfect fit and Air raid is always my first choice on all of my vehicles 👍

I bought both the Airaid Spacer and the Taylor Cable Helix Power Spacer, as I am a Mechanical Engineer and I wanted to examine and compare both spacers in my hands before installation in order to select the best product. I have a 2009 Cadillac Escalade with a 6.2L LS engine (400hp stock), and had already installed these items: - DiabloSport I3 computer tuner - K&N Cold Air intake, plastic tube option - Powersports E3 high output spark plugs - Edelbrock 8.5mm spark plug wires When I stacked both spacers back-to-back, there are obvious advantages of the Taylor Cable Helix Power Spacer over the Airaid Spacer. First and foremost, the Taylor spacer has a slightly smaller inside diameter, about 1/8” smaller, than the Airaid spacer. This means the Taylor spacer will have more air compression, resulting in a higher oxygen content. Second advantage, the Taylor spacer reduction vanes are milled in the same direction as the air flow, which means NO WHISTLE. Those two advantages alone made my decision to install the Taylor Cable Helix Spacer, and to return the Airaid Spacer. It took less than 15 minutes to install the spacer behind my cold air intake. I can tell a DEFINITE DIFFERENCE in both power and sound when I get over 3,000 RPM. At lower speeds, I can tell the torque has improved so that the engine does not downshift at slight accelerations. At higher speeds with more throttle, I can feel more power in each shift, and the sound from the cold air intake now sounds slightly deeper and more muscular, no whistle whatsoever. When I punch it with full throttle I can get past 100mph in only a few seconds. Next, I plan to install a set of Kooks long pipe headers and full dual exhaust for another 30hp and more miles per gallon.

ok well first soo easy to install just take your time and it will take 20 mins max. well i have a silverado and i read it does and doesnt work for my truck but i say it does i got an extra 1 mpg but thats bc im driving in the city and a heavy foot. power wise it added some hp and torque nothing to jump around and go crazy but something to still have fun with. also that noise that "sounds like a turbo" not so much but at the same time it does. its kind of annoying since you still hear it over my flowmaster exhaust but you only hear it after second gear so driving slow you dont hear anything until you hit it and if your have the radio on you wont hear anything. oh yeah it also does fit with a k&n air intake system.

I have a 2011 Silverado 1500 LT 5.3L. A year ago I put in my spectre cold air intake and noticed performance increase. This air raid throttle body spacer took it to another level. Faster throttle response, better gas mileage (if you don't have a lead foot), and a cool (almost turbo sounding) whistle from 2250-5000 RPM's. Very happy with this product and excellent customer service.

Came as described, shipped fast. 2012 Silverado LT 5.3. Fits perfect. These don’t make your truck any faster, we do it for the whistle lol

TBS has definitely increased take off power. does whistle but can barley hear it over my nitto trail grappler mt. mpg increased a litlle but nothing to right home about. Easy install and fit well.
