PowerFlex 26 5552 020 Engine Mount Insert for MINI Cooper

The PowerFlex 26 5552 020 (PFF5-207) is a precision-engineered engine mount insert designed to reduce engine movement and improve drivetrain performance. This insert is manufactured from high-grade polyurethane and fills the voids in the factory engine mount assembly, effectively stiffening the mount between the engine and chassis for enhanced throttle response and reduced wheel hop.

Key Features:

• Constructed from Shore 70A yellow polyurethane for street performance use
• Designed as an insert for the large mount in the left side engine mount assembly
• Reduces excessive engine movement during acceleration and gear changes
• Improves power delivery and sharpens shift feel
• Cost-effective alternative to complete mount replacement
• Simple installation without requiring full mount removal
• Extends the life of factory rubber mounts by limiting deflection
• Manufactured in the UK with ISO9001 certification

Performance Benefits:

• More connected and responsive shifting with reduced slop
• Better throttle application due to controlled engine movement
• Improved traction during hard acceleration
• Enhanced driver feedback and chassis control

This street-spec insert provides approximately 25-30% increased stiffness over stock rubber mounts while maintaining acceptable noise, vibration, and harshness (NVH) levels for daily driving. Some increase in NVH at idle should be expected, as this is inherent to stiffening the connection between the engine and chassis. The polyurethane construction offers superior durability compared to factory rubber components.

Technical Specifications:

• Material: Polyurethane
• Durometer: Shore 70A (Yellow)
• Application: Left side engine mount assembly - large mount insert
• OEM Cross Reference: 22116783094
• Alternative Part Numbers: PFF5-207, 265552020, 5055676512406
