Hi SDnatist
Just my pennies worth , The chaps are correct about under bonnet air filters ,They will suck warm air , the better way is move the air filters forwards to the area between the grille & rad , If you look at where your intakes are connected to each side of the rad you will see a plastic molding which you can remove , So what i ended you doing was have some tube bent up to the same shape of the plastic tubes & got hold of some rubber tube to go thro' the holes each side of the rad & in the area behide the grille


If you do a search on this subject you should see a few setups .
Cheers
