Frequently Asked Questions
Is this for the Left (Driver) or Right (Passenger) side?
Both! 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. (Note: You will need to select a quantity of two (2) at checkout if you intend to replace both mounts).
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.
Should I replace both engine mounts at the same time?
It is highly recommended to replace engine mounts in pairs. Since both mounts support the exact same engine weight and endure the exact same lateral G-forces, if one mount has failed and sagged, the other is undoubtedly compromised. Replacing just one will put uneven stress on the new mount, causing it to fail prematurely.
Why should I buy Genuine Porsche over aftermarket?
The 911's handling characteristics are incredibly sensitive to engine movement. Cheap aftermarket mounts often use inferior, solid rubber that transmits harsh, rattling vibrations straight into your carbon fiber and leather cabin. Genuine Porsche mounts utilize the correct factory fluid-filled dampening rates to provide a perfect blend of structural rigidity and grand-touring comfort.
