Err, won't the impact bar get in the way? Wait, let me guess - you've removed yours?
TBH you'd be better off making a shroud out of ABS plastic between the bumper grille and the sides of the IC. The ducted air won't be able to go anywhere except through the IC, substantially improving cooling performance. Although you won't end up with 'look at me' evo mods
sorry but a good mould costs alot of money,
then theres time and materials so they wouldnt be cheap.
i wouldnt be making them so not really worth my time
