    5 Top Rated Questions

    Can this fit a 2.5 L

    • The Airaid PowerAid Throttle Body Spacer is designed specifically for the 4.0L, and would be incompatible with the 2.5L.

    Helpful (1)

    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.

      Review from Airaid PowerAid Throttle Body Spacer (91-06 4.0L Jeep Wrangler YJ & TJ)

      Airaid power

      I added the airaid spacer with the BBK 62 throttle body. I had already put on a KandN cold air intake. The combo is the best modification you can get legally in California. I can feel and hear the power and smoothness. Very happy.

      Woah

      Unexpected performance gains! Might have to do with changing the angle where the gas pedal attaches to the throttle body, but the throttle response is a little quicker. Paired with a 62mm throttle body and a cold air intake.

      Review from Airaid PowerAid Throttle Body Spacer (91-06 4.0L Jeep Wrangler YJ & TJ)

      Throttle body spacer

      The Airaid throttle spacer is a definite help in throttle response and off idle torque. I tend to disagree with the video on the install, claiming little “power” gain. This is only designed to help on the lower end of the spectrum which it does nicely. I had already installed a CAI and I think it was a great compliment to the spacer. The whistle is pretty cool also!

      Easy to Install

      This was an easy install. However, I could only see where I needed (2) of the bushings on my TJ. Seems like a little boost in power but not very noticeable. We will see if it improves gas mileage.

      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.

      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.

      Review from Airaid PowerAid Throttle Body Spacer (91-06 4.0L Jeep Wrangler YJ & TJ)

      Questionable Performance Gains

      I installed this item in conjunction with a KandN Wrangler 57 Series FIPK Performance Cold Air Intake 57-1514-1 which is a performance enhancement with dyno run sheets showing average HP and Torque increases. No actual performance dyno run sheets or numbers are given for the Airaid Poweraid Throttle Body Spacer but it did give me a shocking view of my throttle body which was filthy so cleaning it as well as installing the new equipment has provided an actual performance gain and better fuel economy.
