Sold each - 2 required per car

High-quality air box mounting rubber buffer designed for Porsche 928S models with engines M28.21 and M28.22.

This component acts as a spacer and vibration-damping mount for the air filter housing, ensuring correct positioning and reducing movement within the engine bay. It plays a key role in maintaining stability of the intake system and preventing unwanted vibration or wear.

Manufactured from durable rubber compound, this mounting buffer is designed to withstand engine bay heat, vibration, and environmental exposure while maintaining flexibility and structural integrity.

An essential replacement part for maintaining proper air box alignment and overall engine bay condition.

Key Features

• Direct replacement air box mounting rubber buffer
• Suitable for Porsche 928S (M28.21 and M28.22 engines)
• Supports correct positioning of air filter housing
• Absorbs vibration and reduces movement
• Durable rubber construction for long-term performance
• OEM-style fit and function

Function and Purpose

This rubber buffer acts as a mounting spacer and vibration isolator for the air filter housing.

It helps to:

• Secure the air box in its correct position
• Reduce engine vibration transfer to intake components
• Prevent movement or misalignment of the air filter housing
• Protect surrounding components from wear and stress

Why Replace Your Air Box Mounting Buffer

Over time, rubber mounting components can degrade due to heat and age.

Common issues include:

• Cracking or hardening of rubber
• Loss of flexibility and damping ability
• Air box movement or instability
• Missing or deteriorated mounts

Replacing the buffer restores proper fitment and helps maintain engine bay integrity.
