NIBBI Racing Parts - Upgraded Aluminum Air Intake Manifold (Black Glue) for High Performance Speed Modification of GY6 Engine 125CC-150CC Review

I like that the crankshaft breather tube can be placed on top of the intake. However, the dimensions confuse the descriptions. Some say 45 screw holes, some say 49. I'll try to help with pictures.

This was the best intake manifold I have ever bought. Compared to the NCY, this one seals the carb better, but has the same problem of the o-ring on the bottom gasket melting, and it's kind of a one-piece thing. I'm waiting to see if I can buy a pack of o-rings to give the product 5 stars.

Quality Control Disappointing. I'm not sure if the device has been on the shelf for a long time or if it was of poor quality. The polished finish is on the inside and that was just a major disappointment, I didn't expect to have to polish it myself, it worked but great care was required and the part should never have been shipped.
