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 problem areas before problems occur with our Cast Aluminum replacement. Made to fit just like the stock unit, this replacement will get your coolant system back in top shape quickly. Broken, cracked, or brittle flanges are no longer a problem. Take the worries out of your morning commute with an inexpensive piece of mind.
