Yeah mate, don't buy anything from eBay unless it's a name brand.
Learnt this the hard way :D
I fell into this one too and bought this a long time ago.
The brackets fits in well cause of the grooves, BUT it's very very very flimsy
Now it's just decoration on the engine
Currently saving up for a CAI then I'll replace this crapy thing :D
DON'T BUY THIS, BUY THE REAL THING :D
