Repaired an intercooler
I bought an intercooler for cheap from a friend and it needed a new fill neck. The old one was crushed when his front-clip was shipped. It wasn't in stock so Amazon had to special order it. High quality peice and was welded professionally buy a local aluminum fabricator. Works awesome.

Filler neck good but threads are terrible.
3 stars because the filler neck itself welded decently. When I was trying to remove the overflow fitting (threaded with sealant like normal) to switch from the pre-installed barbed fitting to an AN fitting, the fitting cracked off and pulled the threads out for the new fitting. Had to scrap and put a better quality filler neck on which was a major delay for the project. *Even when installing a hose onto barbed fitting, be careful! It will crack off!*

Great product, but it came with sealant on the fitting
The fill neck is awesome, only issue I got was the fitting was sealed and cannot be removed, otherwise the fitting will snap from the neck. This for me is a bit of an issue as it will be hard to tig weld around that spot. Again, product is great, but it will be even better if the fitting is not attached to the neck from the factory, let the user do that.
