| Engine Air Filter | 2 | Porsche #991.110.13000 | Suncoast Air Filter Kit |
1 We have been strongly advised to stick with Porsche branded air filters as we have heard of non-insignificant issues with aftermarket air filters.
| 1. Following the method outlined in our Porshce 911 (991.1) Rear Bumper Removal Guide we removed the rear bumper to gain access to the engine air filter box. |  |
| 2. Next we used T25 (Torx) socket socket to remove 7 of bolts securing the air filter cover on the top and each side. |  |
| 3. With the filter cover unsecured, we tilted the filter cover down and then lifted out of the slots holding it in position to reveal the two engine air filters. | |
 |
 |
| 4. Noting the orientation of each of the air filters, we then removed each of the old air filters, and used a cloth to ensure that the air filter housing is completely clean and free of debris. A degreaser may be helpful if there is a particular build up on the housing. | |
| 5. Next, we installed the new air filters in the same orientation in which they were removed. They should only install properly in the correct orientation. Tip, using a Sharpie fine point marker, we write the installation date on the air filters to prevent any confusion. |  |
| 6. Finally, we reinstalled the engine air filter housing cover by slipping in the bottom tabs and reinstalling the 7 cover bolts with the aide of a T25 (Torx) socket socket. | |
| 7. We returned to our guide, Porshce 911 (991.1) Rear Bumper Removal Guide to reinstall the rear bumper. | |
