Original Product: Air-Cooled Porsche 911 Oil Cooler NACA Duct
I’m proud to introduce the released version of my G-body oil cooler NACA duct!
Note: The following information is for educational use only. Before proceeding please read my disclaimer page.
Functional duct to flow additional air directly in the path of the front oil cooler. Designed to blend in with the surrounding black rubber trims of the impact bumpers for a period-correct, OEM+ look.
Material
3d printed nylon that is UV, chemical, and heat resistant, in a black-dyed textured finish.
Compatibility/Fitment
Fits all 74-83 G-body 911s with stock front bumpers, horns, and right side oil coolers. It is slightly recessed into the front bumper so your shins will thank you as you walk closely around the front of the car. 🙂
Left side duct also available for custom applications such as additional oil coolers or AC condenser. Bolts on the same way as the right side but interferes with stock washer fluid tank. Duct outlet can be trimmed to fit whatever you mount in that area.
Installation
About 20 minutes and fits with the factory horns and aluminum oil cooler crash plate in place. You do need to drill 1 hole in the crash plate directly behind the bumper but you can keep it in place to protect the oil cooler in case of a front end impact. Completely invisible from outside and no mods needed to the chassis or bumper itself.
Here is a short video summarizing the install process. Note this is the earlier version without the textured finish:
Cooling Performance
On a 3.0L CIS engine with a 28 tube brass oil cooler I was able to get up to 9 deg F in oil temp reduction during summer triple digit temps at highway speeds. Your results will vary depending on your engine and cooling setup. Trombone coolers won’t see much difference.
Yes, this part has been on the Nurburgring!
