Please tell me exactly what this is designed to do and how it does it? Thanks

  • Hello, the Airaid PowerAid Throttle Body Spacer (91-06 Wrangler YJ & TJ w/ 4.0L) is a piece of metal used to change the airflow into the intake manifold. The spacer is bolted on the back of the throttle body, downstream of the main airflow. This is strictly an aftermarket enhancement used to increase the fuel economy, torque and horsepower. It basically directs the flow of air into the manifold to maximize the volume that goes into the intake.

    Airaid throttle body

    I added this throttle body with the Airaid air intake to my 2003 TJ Sahara with six cylinder engine. Easy installation, quick installation, and it has added some performance power AND BETTER GAS MILEAGE.. If you are planning any updates to your Jeep, this should be the first one you do!!

    I simply like this product because it gives a real nice whistle when you accelerate. However there really isn't any performance gain.

    Power Difference Noted

    Real easy install. The directions didn't exactly match my application, but I figured it out. I do notice a difference in power, especially 2nd and 3rd gears. It would help if the torque specs were included.

    Great Addition to the 2.5L Wrangler

    I installed this throttle body spacer along with a cold air intake. The installation was a breeze, and I would definitely tell the difference in performance. I have 31" tires on my Jeep and this addition has helped move me down the road with more power.
