Description
The NRW-Design Silicone Throttle Body Coupler Set is a premium, long-term replacement for the factory throttle body and plenum couplers found on BMW’s high-revving S65 and S85 engines. These OEM rubber pieces are known to degrade over time—becoming brittle, leaking, or collapsing under heat and pressure. NRW Design’s precision-engineered silicone couplers eliminate those issues, providing a permanent, heat-resistant solution for both street and track use.
Constructed from multi-layer high-performance silicone, these couplers are engineered to handle extreme temperature variations without cracking, deforming, or losing their seal. Each kit includes durable stainless-steel clamping hardware for a secure, leak-free installation that will last the lifetime of your vehicle.
