ECS E46 M3 Silicone Radiator Hose Kit
Unlike factory rubber hoses, silicone can withstand higher temperatures and pressures with minmal wear. Rubber will wear out and weaken so don't let it bite you when it counts! Silicone has been proven during extreme racing conditions and won't be the weak link that ruins your day.
This kit is specifically designed for the enthusiast that wants uprated cooling hoses, but also wants to address the heat-cycled plastic connectors and o-rings that are also prone to failure in higher mileage or older vehicles.
This E46 M3 ECS silicone hose set replaces two hoses -
11537830716, upper radiator hose
11537830715, lower radiator hose
