china airgap intakes on ebay

I've seen first hand how the knock off pos was such a poor fit that it was not possible to make it seal. A bit of work for a 4.5 inch grinder?

The angle of the bolts holes was NOT the same as the holes in the head.
Nor were the angles of the head faces the same as the manifold.
It was beyond being even remotely fit for purpose.......
