My brother-in-law, Matt, recently traded in his 1997 Jeep Wrangler Sport on a 2004 Rubicon.  However, before he took the '97 to the dealership, he was smart enough to remove any aftermarket add-ons and replace them with the stock equipment he had wisely stored away in the attic.  So, while my family and I were visiting for the weekend, Matt and I slipped out at the first chance and commenced installation of his throttle body spacer.  I have a PowerAid throttle body spacer on my Jeep but Matt decided on a Trans Dapt because it was guaranteed not to whistle like the PowerAid and it was around $25 cheaper.  I will admit that the Trans Dapt was indeed quieter than the Poweraid, but I think the Poweraid is a better quality product.  None of the bolts for the Trans Dapt were the right length and the spacers for the throttle linkage bracket were steel instead of aluminum like they are for the PowerAid.  Anyway, we did manage to get it installed without any real problems.  Here are the very simple instructions for you to install your own.

The first thing you have to do is remove the 4 bolts that hold the throttle body to the air intake manifold (see picture 1, red arrow).  While you are removing bolts, go ahead and remove the 2 bolts that secure the throttle linkage bracket (see picture 1, yellow arrow).

Now it's time to slide the throttle body spacer into position between the air intake and manifold (see picture 2, red arrow). The spacer should have a label indicating which side should face the manifold.  Since this Jeep is so new, we left the stock gasket on the throttle body (this gasket will be in between the throttle body and the spacer) but did add a new one (provided) between the throttle body spacer and the manifold.  Once the spacer is in place, we lined up the 4 new, longer bolts provided and secured the throttle body and spacer to the intake manifold (see picture 3).

Once the spacer was secure, we inserted the spacers in between the throttle linkage bracket and its original mounting point which raises it about an inch.  Then we bolted the bracket back on with the provided longer bolts (see picture 4).

Once everything was tightened up, we started it up and made sure the throttle linkage worked correctly.  Everything worked fine.  And, no whistling.

That wraps up this Outdoor-Joe Project.  I hope it helps with your throttle body spacer installation.  Be sure to check back for more off-road projects.  If you have any questions, send me an e-mail.
