Step 6 - Installing The Upper Radiator Shroud Panels
 
Only the upper panel will be installed now. The bottom panel and the side panels will be installed after the intercooler is installed. These panels help seal off the air passage and improve the efficiency of the Intercooler and cooling system. The increase in the frontal area improves air flow compared to the factory shrouding. The sides will now be more closed off, with the new panels providing better airflow through the A/C evaporator and the radiator. If the panels require any additional trimming, use tin snips to cut the plastic.
 

Install The Upper Panel


This panel mounts in the mouth of the front opening between the bumper and the bumper supports of the car, as seen in Photo 6-B. The plastic panel comes pre-drilled for the two outside holes, which you will use for alignment to mark and drill the center hole.
The upper panel is also used on the M2 Miatas. The M2 Miata does not have a center mounting hole like the M1 Miatas.

Hardware Package B-1

  • Mount so the textured side is visible and the three small mounting holes are at the back. Pull the bumper down a little so that you can slide the panel into position.
  • Push the new plastic mounting plugs partially in through the bumper on the two sides. Do not push them in all the way; this step is for alignment to mark the center hole for drilling. Mark the hole for drilling.
  • Remove the Upper Panel and drill using a 3/4" hole saw or a smaller drill bit and finish with a utility knife.
  • Reinsert the Upper Panel into the bumper and insert the 3 plastic plugs about half- way in. Use the supplied Zip-Ties and loosely attach the back section of the Upper Panel as shown in Photo 6-C.
  • Bend the Zip-Tied tabs up. This will improve the air flow into the radiator area as shown in Photo 6-B.
  • Push the plastic plugs securely in place.
  • Tighten the Zip-Ties and cut off the ends.

You will complete the remaining panel installation after the Intercooler is installed.
