well taking the front bumper off is easy, torx screws in the wheel arches, behind the lower vents and behind the grill, then it slides off two brackets either side, takes about 15mins when you know where everything is. The headlight is two screws top and two bottom and then take the headlight cover off and remove the wiring clip off at the back. Then you take the battery clamp off and either tilt the battery back or take it off. The airbox is held on with two screws and is cliped onto the intake manifold (u also have to remove the maf wiring clip) and the snorkel is held on with one nut onto the side of the engine bay. Once you have that out you then need to take the back of the headlight surround off which is three of them split pin clips then that slides out, replace that with the new one and refit the battery then line the new snorkel up to the airbox and see how much you have to grind away. After you have done that fit the snorkel to the car and refit the airbox and then refit all the trim the oposite way round, like I say it took me and my mate 2 hours but was well worth it
