hey all just threw in a K&N panal filter an realised the mounts on the lower casing of my air box are all broken off? i assume someones just been heavy handed with it in the past but anyone got one? got a price for one? i assume its got to be the cheaper component as the upper casing holds all the plugs and connectors? its hardly vital would just stop the box from moving about! there doesnt seem to be many S4's up for breaking!
