hi weve got the bar and the rubber mounts, it's the metal brackets (x2 each side i think??) which bolt to the chasis that the through bolts from the rubber mounts go through that were after. weve got the air filter but not sure what secures it in place in the engine bay??
On my bay the air filter sits on a metal lip on the right hand side (as your looking at the engine bay) I have secured mine with Zip ties it's the only way it worked for me
