Because German car manufacturers made so many coolant piping pieces of hard plastic, it is common for these parts to break over the years. After thousands of miles and many years of hot coolant contact, it's easy for these parts to degrade and become brittle. Replace those trouble areas before problems occur by using the iABED Industries Cast Aluminum Thermostat Housing Kit.
Made to fit just like the stock unit, this replacement will get your cooling system back in top shape quickly. Broken, cracked, or brittle flanges are no longer a problem.
