Bobby,yes,it fastens on at 4 points.I don,t know the technical description of the fastenings but the 2 at the front of the engine bay and the upper right hand one are all the same,they are about 4 cms high and screw in to top of engine and have like a ball on top that the engine cover pops down on to. ie.push fit.The rear left top one is basically a bolt or screw with a rubber collar and the engine cover slides under it.(your car may already have one or more of these)I can't imagine that they would cost much.The 2 at front of engine screw into a plastic type moulding,it had holes pre drilled but they had no threads and we had to use a 6ml tap.Only took about 10 mins to complete.Strangely we looked under the bonnets of about 6 cars,some had no fasteners at all whilst some had one fastener-can't understand why if Seat do all this as a cost saving exercise they still have spare fasteners on some cars doing nothing!Hope this helps.
