IMS Bearing Upgrade Kit with Full Ancillaries – Essential Reliability Upgrade for 997 Porsche M96/M97 Engines

This IMS bearing upgrade kit includes everything needed to replace and enhance the intermediate shaft bearing in Porsche M96 and early M97 engines. Designed for early 997.1 manual models, this complete package includes the upgraded bearing assembly, new hardware, seals, exhaust clamps, sleeves and all required ancillaries to streamline installation.

Fits:

• Porsche 997 MK1 Carrera 2 3.6L 2005 (engine code M96.05)
• Porsche 997 MK1 Carrera 2S 3.8L 2005 (engine code M97.1)**
• Porsche 997 MK1 Carrera 4 3.6L 2005 (engine code M96.05) 
  
• Porsche 997 MK1 Carrera 4S 3.8L 2005 (engine code M97.1)**
  

What the IMS Bearing Upgrade Kit Does

This complete kit:

• Replaces the vulnerable original IMS bearing with a fortified, precision-engineered alternative
  
• Reduces friction and improves lubrication stability
• Protects the intermediate shaft from premature wear
• Prevents metal debris contamination inside the engine
• Restores confidence in long-term engine reliability
• Includes all necessary hardware, clamps, sleeves and seals for a seamless installation

Designed to meet the demands of both road use and high-performance driving.

Why IMS Bearings Fail in Porsche M96/M97 Engines

Common causes include:

• Lubrication starvation, leading to ball bearing scoring
  
• Seal degradation, causing grease loss and overheating
  
• Contaminants entering the bearing assembly
• High engine speeds, accelerating wear
  
• Age-related material fatigue
• Inadequate internal lubrication flow in the early intermediate shaft design

Symptoms are often subtle—or non-existent—until severe engine damage has occurred.

Why the IMS Bearing Should Be Upgraded

Upgrading the IMS bearing provides:

• Prevention of catastrophic bearing failure
• Significant extension of engine lifespan
• Peace of mind for owners of 996/997/986/987 models
• A stronger, more stable bearing with improved lubrication path
• Reduction in maintenance costs over time
• A complete installation solution thanks to included ancillaries

This kit is essential for any Porsche owner planning long-term stewardship, spirited driving, or engine rebuild work.
