Fitted my K&N panel filter today (thanks Norm)
and was tightening up a few jubilee clips that seemed a little loose around the whole intake generally.
Was wondering what exactly is the purpose of the box attached to the side of the final pipe before it goes into the engine (sorry for being non technical)??
Can you replace/upgrade these?? only I'm limited for power on my N/A 1600 obviously, but I wouldn't mind improving throttle response and things like that.....
what ya reckon?
