Part number: IS - EMK - Z33. This ISR Performance billet engine mount set is specially designed for Nissan 350Z and Infiniti G35. It features a billet two - piece design. You can use a polyurethane bushing for a true insulated mount, or simply replace the inserts with solid aluminum (sold separately or as an initial option) to have a fully solid mount. It's a must - have upgrade over OEM rubber mounts, offering a stronger mount in a more compact size.

Using this engine mount set is easy. First, make sure your vehicle is parked on a flat and stable surface. Then, carefully remove the old OEM rubber mounts. Next, install the new ISR Performance billet engine mounts in place. When choosing between the insulated and solid mount options, think about your driving style and needs. For daily driving, the insulated option might be more comfortable. If you're into high - performance driving, the solid mount could be better. As for maintenance, regularly check the mounts for any signs of wear or damage. Keep them clean and free from dirt and debris. If you need to replace the solid aluminum inserts, it's a straightforward process, but always follow the included instructions.
