Just got through installing my Stillen airbox and filter. Already had a Z-tube on there.

OK, this was easy, almost too easy. Just wondering what I missed if anything.

First of all there were 4 bolt and nuts and washers provided. WTF do I do with these? There was no need for them UNLESS I'm missing something.

Second, The only thing attaching the airbox is the ONE bolt on the strut tower. Then the tube connected to the airbox and filter directly. Seems like there should be something else to stabilize it.

Lemme know if I missed something.

 

Its just the bolt that goes on the strut tower and the four bolts that bolt the MAF sensor assembly to the filter.

Seems like you did everything alright... its a pretty easy install.
