Mishimoto Black Silicone Hose Kit for 1999-2009 BMW E46 3-Series & Z4 (MMHOSE-E46-NONMBK)

Fits select 1999-2009 BMW E46 3-Series and Z4 models (2.5L, 2.8L, 3.0L, 3.2L).

The Mishimoto MMHOSE-E46-NONMBK silicone hose kit is engineered to replace the failure-prone factory rubber hoses on your BMW. Over time, repeated heat cycles cause original rubber to become brittle and crack, leading to potential coolant loss and overheating. This kit is constructed from high-grade silicone for superior temperature and pressure resistance, ensuring a significantly longer service life than stock components.

For a straightforward installation, these hoses feature pre-attached, stock-style quick-disconnect fittings and include fresh O-rings to maintain a factory-perfect seal. Designed for versatility, this kit is fully compatible with both the original equipment radiator and the Mishimoto Performance Aluminum Radiator.
