Upper & Lower Radiator Hose Set, Vargas - E82 135i, E9X 335i, E89 Z4 35i (N54)

Top and bottom radiator hose for N54 engine used on E82 135i, E9X 335i, and E89 Z4. Silicone hose with aluminum fittings make these hoses far more durable than a stock hose. Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age, and can eventually fail, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation. Replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

These are silicone version of the stock rubber hoses. Silicone hoses are much more durable than stock, hold more pressure, and retain their flexibility longer. While not indestructible, silicone holds up much better than rubber in high-stress engine builds and is more resistant to heat. While not a performance upgrade, this silicone cooling hose offers greater reliability and long-term durability than rubber. You'll never have a leaking plastic tube again! Additional silicone hoses are also available to complete your N54 cooling system upgrade. To further eliminate plastic we also strongly recommend an aluminum radiator.
