Installation Instructions – 1992 Jeep Wrangler Helix Power Tower Plus

Project Time: About 1 Hour

Step One – Remove the rubber duct/diffuser that goes between the throttle body and the air cleaner housing.

  1. Use a small screw driver to release the plastic clamps, lifting up under the teeth slightly
  2. Place the duct aside, clean the interior if needed

Step Two – Remove the throttle cable and if you have a suicide throttle (interior hand throttle) cable remove it too…

  1. Use a small screw driver to pry the throttle cable end off the ball joint (Red Arrow)
  2. On my particular jeep I have an interior hand throttle control, its cable comes off by removing a hairpin clip (Yellow Arrow)

Step Four – Remove the old gasket material

  1. Remove the old gasket material (Red Arrow)
  2. You may wish to stuff a clean lint free rag into the mainfold opening
    (so nothing drops into the manifold)
  3. Clean the surfaces where the gasket was in contact with using throttle body cleaner

Step Five – Thoroghly clean the throttle body assembly (some basic tips)
I am not going into great detail as there are many docs and videos available showing this process

  1. Always use a throttle body cleaner, other cleaners may cause damage
  2. A well ventilated area is important (Outdoors is best)
  3. Rubber gloves and eye protection should be used during the cleaning process
  4. Lint free materials should be used, as well as a catch basin to work in
  5. Don’t scratch the walls or plate when cleaning, let the cleaner do the work
  6. Remove the idle speed stepper motor and clean it thoroughly as well as the ports it mates into
  7. You may lightly lubricate the pivot points of the plate when finished

Step Six – Installing

  1. Put the new Power Tower PLUS (engraved side toward the throttle body)
  2. Make sure you have a gasket above it (between the throttle body and Power Tower)
    and below it (between Power Tower and intake manifold)
  3. Install the four 6mm x 50mm bolts and 4 washers by hand first
  4. Tighten bolts evenly to 10Nm (89lb/in) (Yellow Arrows)

Step Seven – Linkage plate re-alignment

  1. Included in the kit are 3 1″x6mm spacers that go under the cable linkage plate
  2. Remove the three stock bolts holding down the linkage plate (Yellow Arrows)
  3. Raise the linkage plate and place the three spacers under each leg and use
    the new 40mm x 6mm bolts to secure them
  4. Tighten bolts to 10Nm (89lb/in) (Yellow Arrows)
