        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.

            Made the hood look great and added plenty of ventilation. Loved the metal template. Made cutting a breeze and took away the worries of it sliding and messing up the cuts. The only thing is to be careful if a nut is tight it will make the affixed studs spin. Overall it is a great product.

            This piece was super easy to install and a direct fit, haven't noticed any difference in horsepower, but I didn't expect to. Just a great peace of mind knowing my engine is getting optimal air intake

            Doesn't fit with certain aftermarket intakes.

            It's possible the part won't fit if you're running an aftermarket intake, When I went to install mine it caused my intake pipe to collide with the brake booster, and not fit. :/

            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.

            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!

            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.
