I bought these from a nice NAMer on the Marketplace. They came with matching upper and lower grilles as well (not sure what I think about those yet, I was mostly in this for the cowls but maybe when I'm bored one weekend we'll see about at least the lowers. Really not crazy about the upper.)

So they came yesterday and I went at it this morning. Whole thing took 10 minutes and having small hands was a major plus (honestly, I'm not sure if someone with larger hands could do this themselves). They just screw right on, the screws go through little brackets that clamp the underside lip of the cowl opening.

The finished product (sorry the pictures suck, these are taken in my extremely crowded garage):





I was sort of skeptical (like "I don't know if I'm going to like these, but let's see how it goes") as I installed them...but now that they're on I LOVE them!

 

Those look sharp ML! And the stripes, not so ganky.
