E9X E8X Cabin Filter Bolt Repair Kit

E9X E8X Cabin Filter Housing Mounting Screw Repair Kit (Stainless + Brass Upgrade)

Stripped or spinning cabin filter housing screws are a common issue on E9X chassis cars. This kit provides a permanent, high-quality solution using durable materials that outperform the factory setup.

Designed to restore proper mounting of the cabin filter housing, this kit replaces damaged plastic threads with precision brass inserts and upgraded stainless steel hardware for long-term reliability.

What’s included:

• High-quality stainless steel mounting screws
• Precision brass thread repair inserts
• Installation drill bit (correct size for inserts)
• Thread-locking adhesive for secure insert installation

Key benefits:

• Permanently repairs stripped or failed mounting threads
• Brass inserts provide strong, repeatable threads in plastic housings
• Stainless steel hardware resists corrosion and seizing
• Eliminates loose or unsecured cabin filter housings
• Clean, OEM-like fitment

This is the proper fix if your cabin filter housing no longer tightens down or the screws just spin in place. No more temporary fixes or oversized screws that damage the housing further.

Everything needed for the repair is included—no guesswork on drill sizing or sourcing additional materials.

Built for long-term durability and repeated service without thread failure.

IMPORTANT: Hand tighten only! Overtightening or use of power tools to tighten bolt will result in damage.
