Mishimoto Blue Silicone Hose Kit for 1999-2009 BMW 3-Series (E46) and Z4 - MMHOSE-E46-NONMBL

Fits select 1999-2009 BMW 323i/Ci/is, 325i/Ci/xi, 328i/Ci/is, 330i/Ci/xi, and Z4 models (2.5L / 2.8L / 3.0L / 3.2L).

The cooling system is a notorious weak point in the BMW E46 and Z4 platforms, where factory rubber hoses eventually become brittle and fail. The Mishimoto Silicone Hose Kit provides a direct-replacement solution designed for superior durability and heat resistance. These hoses are engineered to withstand the higher temperatures and pressures associated with performance driving, ensuring your cooling system remains sealed and efficient.

This kit simplifies installation by including pre-attached, stock-style quick-disconnect fittings and new O-rings, maintaining factory-level fitment while offering an aesthetic upgrade. Designed to work seamlessly with both the OE radiator and the Mishimoto Performance Aluminum Radiator, this kit is an essential preventative maintenance step for any high-mileage or track-driven BMW.
