BMW B46 B48 Boost Pipe Retainer Clip - Part Number 13718642239

Stop boost leaks before they start. This genuine factory retainer clip secures the turbocharged intake boost tube for B46 and B48 petrol engines, keeping the charge air connection sealed and locked under load. Ideal when upgrading to an aluminium boost pipe or replacing a tired or missing lock ring, this is the exact OE snap clip you need for a leak-free, rattle-free fit.

Why this OE lock clip belongs on your car

• Authentic BMW component for perfect engagement and long-term reliability
• Prevents pressure loss, hesitation and limp mode by keeping the boost pipe firmly seated
• Correct clip for alloy boost tube upgrades and intercooler pipe refresh on B46 and B48 engines
• Durable spring-steel construction to OEM specification for repeated removals and refits
• Simple installation and a proven fix for many boost related issues

We have used this clip extensively in-house on our own B48 projects, and customer feedback has been consistently positive for secure fitment and restored boost pressure.

Perfect for upgrades and maintenance

Pair this OE snap ring with popular aluminium boost tube kits, including Masata, for a robust, leak-resistant connection. It is also a direct like-for-like replacement for worn or lost factory clips on compatible B46 and B48 powered vehicles.
