The Professional Solution for G-Chassis "Hot V" Reliability. Don't let a "Low Coolant" warning sideline your luxury 7 Series. The BMW N63R engine in the G11 and G12 houses its turbochargers in the high-heat "Valley of Death," causing factory rubber lines to harden and leak. This GryphonTek Signature Series Kit is the definitive upgrade: replacing aging factory hoses with Multi-Layer Reinforced Silicone custom-molded to exact OEM specifications for a perfect, leak-free fit.

  • Molded Precision: Every hose in this 4-piece kit is custom-molded to match the exact factory angles and geometry. No kinks, no stress on fittings, and no custom cutting required.
  • Zero-Guesswork Installation: We include a Hose Correspondence Map with every kit. This visual guide ensures you identify and install each of the 4 lines in the correct position, saving time and preventing costly errors in the tight N63R engine bay.
  • High-Temp Resilience: Engineered with multi-layer reinforced silicone that stays flexible under extreme thermal stress, preventing the brittle cracks common with factory rubber.
  • Direct Fitment: Tailored specifically for the G11/G12 750i and 750iX layout, ensuring a professional-grade repair that looks and performs better than OEM.

Why Upgrade / Why Choose

The N63R is a powerhouse of a V8, but the radiant heat trapped in the engine valley eventually cooks the standard cooling hoses until they leak. Unlike generic "cut-to-length" hoses that can collapse or kink when bent into the N63R's complex cooling paths, our kit features Pre-Shaped Silicone. This ensures maximum flow and a permanent seal that can handle the intense vibrations and heat of a modern BMW performance engine.

The GryphonTek Signature Series Kit isn't just a replacement—it’s an engineering upgrade. By providing the exact factory pathing with superior materials and a clear installation map, we eliminate the frustration of cooling system maintenance. Fix it once, fix it right, and maintain the prestige and performance of your G-Chassis 7 Series.
