Solved my coolant leak and looka great
Posted by Jeff B. on 3rd Apr 2017
Had a lot of issues with leaking coolant on my 1.8T after deleting the heater core and factory oil cooler. This flange fit my need perfectly, with a snug fit for the coolant temp sensor and o-ring, and just the single outlet I needed for the upper radiator hose. Took a while to arrive, but was well worth it now that I have a reliable cooling system once again.

finally a permanent coolant flange
Posted by Victor on 28th Sep 2015
I bought the billet cooling flange a while back when the pre-sale was happening. It took me a while but I fanally installed it yesterday 9/27/15. The installation went smooth just like installing the original crappy plastic Audi mk1 TT flange that's prone to breaking. The new flange looks great too bad is somewhere where you really can't show it off to people, but I'm glad to know I won't have any cooling leaks due to this new billet cooling flange.

Nice product, a little expensive on the pocket but will save money and hassle of replacing the plastic OEM flange over and over. Would recommend to friends and fellow vw owners, thanks for making a great product.

Decent product for a decent price
Posted by Travis @ WOT Performance on 11th May 2015
Not too large like other products (4y hose flange). It could definitely use some better welds. I have no concern about leaking being and issue but better looking welds would help improve the aesthetics of the piece if looks is important to you. The welder obviously didn't have his gases set correctly for a clean and crisp weld. Very strong and well made product other than that.

Response from Gruven
Travis, those welds can be ground and polished if you wanted to make it look more seamless. For the price, it was not feasible for us to do that.
