I've seen underhood cowl cover plates made of aluminum that were made a few years ago but can't find any source on the web. Anyone know if they're still being made?

not sure exactly what you're talking about

I think they are made by theses guys

Thanks much Raze! That's what I was looking for...

They do make some sweet cowl scoops too...little pricy but the best I've seen yet...
