Frequently Asked Questions
Why is it important to replace both engine mounts at the same time?
Since both mounts support the exact same engine weight and endure identical lateral G-forces, they degrade at the same rate. If one mount has failed and sagged, the other is undoubtedly compromised. Replacing just one will force the new mount to overcompensate for the old one, causing it to fail prematurely. Replacing them as a pair restores perfect factory balance.
Are the left and right mounts identical?
Yes! This specific Porsche engine mount is non-directional. The exact same part number (99137504902) is used for both the Left and Right sides of the engine. This set simply provides two of these identical mounts so you can complete the entire rear-end service.
What is the difference between part numbers 99137504901 and 99137504902?
Nothing except the production date! Porsche frequently updates part numbers to reflect minor manufacturing revisions. 99137504902 is simply the newest, fully updated factory revision that directly replaces the older 99137504901 number.
Will this kit fit cars equipped with PADM (Porsche Active Drivetrain Mounts)?
No. This specific set utilizes the Standard hydro-mounts. They do not feature the electronic plug-in connector used on vehicles optioned with the Sport Chrono Package / PADM active mounts. Please verify your vehicle's options code before purchasing.
