Heat helps a bit. If it was Di-noc that you used, the corners were probably tough. The pics dont actually look bad. A blow dryer will help make it more flexible to work the corners. One mistake I made was thinking that the heat would 'shrink wrap' the Di-noc. You dont want to do that - just get it warm and flexible. Pressure is what keeps it in place.
K&N Air filter, uh - thats it, NO CAI, NO FSWerks, NO Exhaust, NO Coilovers, NO Tune, Nothing
