Building a front spoiler... need opinions

I wouldn't want one rigidly attached / welded on either.
Newer cars scoop their air off the road and many don't have a grille opening at all. Thye have sand all over the engine too.
Years ago my brother asked, "Recon I could put spark plugs in the 'stang ( 92 model ) with the few tools I have ?" My answer, "Not without compressed air." Then I proceeded to explain, sand enters cylinders.
