One of the biggest issues with older BMWs is the degradation of rubber hoses under the hood. Combine that with the lackluster reliability with older cooling systems and you could have a nightmare on the street or the track. If you do any sort of performance driving, or just want to upgrade to something that will last, then look no further. This complete silicone cooling hose kit for the E36 is made from a triple layer, high grade silicone and Dupont Nomex to provide more efficient heat reduction, increased pressure tolerance, and prevent any degrading over time. This kit comes with everything you need for a 6 cylinder engine.
