I have fitted my induction kit now on my beefa but im concerned about my pipercross breather filter. As you know there is a small black duct pipe that goes into the original airbox. I unclipped this and on the end was a weird circular squeezey clip. Do i cut this end bit off? at the moment i cut the ring bit off pushed my pipercross filter in and tightened with a jubilee clip but the problem is i can pull the filter out with not too much effort. Just wanted to know who has done this properly?
