I just cannot post a photo at the moment but if you remove the grille you will clearly see that there is an upright piece of plastic just before the radiator. Remove part of it so that you can bring the flexible intake forward and over the rad. You might need to secure it with a cable tie. Mine was long enough to rest securely without a tie however I put an aluminium tube in the end to keep it open.
As has been said, these three litre engines can deliver more than enough power for road use but this is a simple and cheap way to gain a bit more.
