NRW Designs S65 Silicone Throttle Body Coupler is a high-performance upgrade engineered specifically for BMW E90, E92, and E93 M3 models with the S65 V8 engine. Available through Turner Motorsport, this premium silicone coupler is designed to replace the factory rubber component, which often deteriorates over time due to heat, oil exposure, and age—compromising air delivery and throttle performance.

Manufactured from multi-layer, high-temperature silicone, this coupler ensures a secure, leak-free connection between the intake plenum and throttle body, helping maintain optimal airflow under both street and track conditions.

Key Benefits:

  • Precision fitment for BMW S65 engines (E90/E92/E93 M3)
  • Multi-layer silicone construction for superior heat and oil resistance
  • Prevents vacuum and boost leaks for consistent throttle response
  • Improves engine efficiency and longevity
  • A reliable replacement for aging or cracked OEM rubber couplers
