Description
The PNH500025-SAMCO (or similar aftermarket/silicone) 2.7L TDV6 intercooler hose is a heavy-duty, often 4-ply or 5-ply silicone, replacement for the standard rubber hose connecting the air duct to the intercooler on Land Rover Discovery 3, Discovery 4, and Range Rover Sport L320 models. It is designed to replace part number PNH500025, which is prone to splitting near the top bend.
Key Description & Features
- Part Number: PNH500025
- Fitment Position: Right Hand Side (RHS / Passenger side on RHD vehicles) – Inlet Side
- Material: Usually reinforced silicone (4-ply/5.4mm thickness frequently reported in aftermarket versions like Samco/Performance brands)
- Engine Suitability: 2.7L V6 Diesel (276DT)
- Operating Temp/Pressure: Generally rated from -60°C to +260°C, with high-pressure resistance, suitable for turbo boost pressures
- Compatibility:
- Land Rover Discovery 3 (2005-2009)
- Land Rover Discovery 4 (2010-2016, 2.7L models)
- Range Rover Sport L320 (2005-2009)
Purpose and Benefits
- Corrects Power Loss: Replaces weak original hoses that split, causing loss of boost pressure, excessive black smoke, and reduced engine power.
- Enhanced Durability: Silicone construction is more durable than standard rubber, making it ideal for the high heat and pressure of turbo diesel engines.
- Direct Replacement: Designed to fit directly into the original engine setup, connecting the intercooler to the intake/throttle body.
