Description

BMW E46 M3 S54 (01-06) Mishimoto silicone radiator hose kit

This Mishimoto hose kit E46 M3 replaces the rubber radiator hoses of the BMW E46 M3 with S54 engine from 2001 to 2006 with silicone hoses. A high-revving S54 that sees lots of track time puts heavy stress on the coolant hoses, and old rubber quickly becomes hard and porous.

The hoses have a dual layer of high-grade silicone with embedded heat-resistant fibres. They withstand up to 166 °C, tolerate more pressure than rubber and fit like the original. You choose between blue and black.

Installation and delivery

Silicone radiator hoses for the S54: one less worry when your M3 is pushed to the limit on track.

Why choose this hose kit E46 M3?

Burst coolant hoses are one of the most common reasons for an early end to a track day. These silicone hoses handle heat and pressure better, last much longer than rubber and fit without modifications. Mishimoto backs them with a lifetime warranty.
