This complete kit is designed to replace both engine mounts and associated fixing hardware in one package, ensuring a correct and reliable installation.

The kit includes:
  •  2 × OE Match engine mounts (99337504909)
  •  4 × Genuine Porsche bolts (90037805501)
  •  2 × Genuine Porsche locknuts (99908421501)

The engine mounts are manufactured to OE specifications, providing the correct balance between support and vibration damping. Built using high-quality elastomer and metal construction, they are designed to withstand heat, load, and long-term use while maintaining consistent performance.

These mounts are suitable for both left and right positions (two required per vehicle) and replace earlier part numbers including 99337504905 and 99337504907.

Including genuine Porsche bolts and locknuts ensures proper torque retention and secure mounting - critical for maintaining drivetrain stability and avoiding issues caused by reused or stretched hardware.

This kit secures the engine to the chassis while isolating vibration and controlling engine movement during driving. It restores smooth operation, reduces noise, and improves overall drivetrain stability.

Replacing both mounts and fixings together ensures consistent performance and eliminates common causes of vibration and misalignment.

Function
•  Supports and positions the engine within the chassis
•  Absorbs vibration and reduces cabin noise
•  Maintains correct drivetrain alignment
•  Ensures secure installation with OE-spec hardware

This kit is essential for preserving both performance and comfort in classic Porsche models.

Over time, engine mounts degrade due to heat, load, and material fatigue. This can lead to excessive vibration, engine movement, and reduced driving comfort. Replacing both mounts along with new genuine hardware ensures proper installation, restores smooth engine operation, and protects surrounding drivetrain components from unnecessary stress.

When to replace
•  Increased vibration felt in cabin or steering
•  Clunking noises during acceleration or gear changes
•  Visible wear or deterioration of mounts
•  Engine movement or misalignment
•  During engine or gearbox service
