DIY in the skill level of (1-10, 10 being most difficult) is about a 4
First, jack the front of the car up, and remove the bumperettes. You do this by first prying open and remove the rectangular rubber cover and then unbolting the two 8 mm nuts. After removing them, unscrew the philips screw that holds the factory fog/parking light and pull it out so that you can disconnect the wires. Unclip two electrical sockets and remove the light. Remove both side wheels and fender liner as shown on bumper removal DIY Remove three screws that hold aluminum oil cooler cover. Before you do this, mark the bracket so that you don’t make the hole for the duct too low. Take the duct and use it as a guide for
marking the hole on the oil cooler you removed earlier. You want to make
the hole as low as you can. (See the arrow pointing the thin line where
the bracket position is marked). You can either use 2.5” hole drill or
“tin snips”, I found using the snips to be the best, 2.5” drill is little
too small and by using snips, you have more freedom to adjust.
Now you’re ready to pull the hose through
the fender to the wheel well area.
Install the oil cooler plate and “flatten” a section of the tube in the between the hub and the oil cooler. This will allow enough clearance so that your wheel doesn’t rub. (You can see the flat part on the photo). Now you need to make similar holes to the fender liner (you need to cut two holes since there are two separate plastic pieces on the fender liner). Put the fender liner in, as you’d be installing it and mark the position where you’re going to make the holes (again, as close as possible to the chassis and as low as possible). Install the fender liner (but leave two lower screws loose at this time) and three zip ties (see the arrows showing the location on the photo). Front zip tie will go under the fender liner, once it’s in place, you can tighten the screws. Now tighten the zip ties and make sure end of the duct is still in its place. (In case you’re wondering, that photo is from previous installation when I did this on my car)
Next, connect the two wires from the fog
light to the wires from the car.
Now, have a beer (or something else to drink) and prepare for the PITA part… Same procedure as on the other side until
it’s time to make a hole to that aluminum plate.
You could remove the A/C assembly so that you’d have good access and you could make a nice hole to through that plate but I chose not to do so. Not very “Porsche engineering” but works. Loosen up the A/C radiator from its bracket
so that you have little better access for making the opening and also pulling
the duct.
Then just do the same things you did on the other side and you’re done! You’re brakes will now have more airflow and that means they run cooler. |
