E60 E61 E63 E64 535d 635d Silicone Intercooler Boost Hose - 1161779629

For E60, E61, E63 and E64 LCI diesel chassis with the N57D30 engine - this is the silicone intercooler boost hose that stops oil misting, eliminates OEM rubber split points, and survives repeated track-day heat cycles.

• Direct replacement for BMW part 1161779629 - same routing, same mounting, no trimming or adaptors
• 5-ply fluoro-lined silicone - resists N57 crankcase vapour, won’t discolour or harden like generic hoses
• Internal stainless steel reinforcement rings - prevents ballooning at 2.2+ bar peak boost (stage 2 & fast road)
• Includes machined aluminium intercooler outlet end + two high-tensile T-bolt clamps - no cheap jubilees
