BMW 1 3 5 6 7 Series X3 X5 X6 EGR / Throttle Housing Upgraded O-Ring

Description

This upgraded replacement O-ring is used on the intake-to-EGR throttle housing connection, forming a critical seal between the EGR pipe and the inlet tract. It ensures a secure, airtight joint where exhaust gases are reintroduced into the intake system.

This part is suitable for vehicles that have or have had a DPF fitted, due to the specific intake/throttle housing seal design used on these variants.

Purpose:

This seal sits at the EGR pipe connection into the throttle/anti-shudder housing, maintaining sealing integrity under boost and EGR flow conditions and helping prevent air leaks at the intake junction.

Features:

• Upgraded high-quality replacement O-ring
• Improved sealing performance over OEM specification
• Designed to withstand heat, pressure, and long-term thermal cycling
• Ideal replacement during EGR or intake system servicing

Replacing this upgraded seal during installation helps ensure a proper, leak-free fit and avoids reusing aged, heat-cycled components that may no longer seal effectively.

Recommended Upgrade:

We also offer a full EGR valve & cooler kit to suit, providing a complete solution for common EGR system failures on compatible BMW diesel engines: https://www.gkrperformance.co.uk/product/bmw-m57n2-318d-330d-525d-egr-valve-cooler-kit/
