Porsche 911 (997) Engine Mount for 2005-2012 Carrera models. Replaces 99737504907, 99737504905, 99737504903. Fits Left or Right. Fix sagging exhaust tips!

The Porsche 911 (997 generation) represents the perfect modern-classic driving experience. However, because the entire weight of the iconic flat-six engine hangs out past the rear axle, the engine mounts are under immense and constant stress. They serve as the critical structural links that maintain the car's legendary balance and razor-sharp handling.

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 (99737504907) 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 the 07, 05, and 03 part numbers?
Nothing except the production date! Porsche frequently updates part numbers to reflect minor manufacturing and durability improvements. 99737504907 is simply the newest, fully updated factory revision that directly supersedes the older 99737504905 and 99737504903 numbers.
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 sagged, the other is undoubtedly compromised. Replacing just one will put uneven stress on the new mount, causing it to fail prematurely.
Why choose OEM over a cheaper aftermarket or "track" mount?
The 997'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 steering wheel and cabin. This OEM mount utilizes the correct factory fluid-filled dampening rates to provide a perfect blend of structural rigidity and luxury grand-touring comfort.
