Amazing quality, looks fantastic. I bought it for my 3sge to see if it would work along with the racerX coolant tree. It isn't compatible with the stock 3sge intake manifold (doesn't clear the throttle body) but I already ditched that. Much better alternative to the stock coolant neck setup. Very happy.

Great product, nice upgrade from the factory filler neck which ended up forming a leak on my car. Install was pretty straight forward. Looks and functions great. Would give this product a 5 out of 5 stars if it came with the O ring to install.
