Identical in its design, but build quality and fitment are a lot of times problems with the professional products parts because of where they manufacture these intakes overseas cheaply. That's why they are able to sell them for so little $.

ou can see right at the top of the lower intake ports there is grinding right where the gasket sits to make the ports so where the gasket doesn't hang over the ports and Sage told me they didn't touch the intake, that's how it came to him. The build quality is quite aparent, but for the price, you just can't beat it.
