Installation

Air tube:

  3. Mark the hole location with a marker and cut out with jig saw.
  4. Drill a 5/16” hole in the lowest point of housing for drainage.
  5. Attach the air tube to housing by working it into the cutout. This takes a little brute force.

  6. Set completed air tube aside until later.

    Hood appliqué

  7. Remove push pins from hood blanket with pry bar. Hood blanket can be left on hood to prevent shavings from getting into engine bay. I also put a piece of card board on the blanket to make sure I wouldn’t cut too deeply.

  1. If factory hood scoop installed, remove that too.
  2. Lay hood down, but do not close all the way. Lay template on hood using feature lines. Tape template to hood once centered and aligned properly.

    Note:This is the hardest, most time consuming part of the install due to the curves of the hood, so make sure to double and triple check measurements so template is in proper position before making any cuts.

  3. Use a 1” hole saw to drill a starter hole where specified. Use jig saw to cut out shaker hole.

  4. Use a center punch on the hole locations specified on the template. Drill locations with a 1/8” pilot hole. The front two holes need to be drilled perpendicular to the ground, not the hood.
  5. Lift the hood and use 1” hole saw on holes that go through inner reinforcement.Don’t go all the way back through to outer hood with the hole saw
  6. Lay hood back down and drill out pilot holes with size indicated on template.
  7. Put appliqué on hood to make sure it fits. Some holes may need adjustment.
  8. Remove template and all tape from hood.

  12. Attach the first mounting bracket as shown below. The alternator bolt is replaced with the ball stud and the bolt on the throttle body is reused. Be sure to use loctite on the threads.


    Note: Do not over tighten ball studs! I accidentally sheared one off. Torque to 40 inch pounds.
