I have a cowl hood molded on my Z32. Well it was. Has cracked numerous times. But when I first got it back from the body shop it got alot of compliments. Flows well with the Stillen kit that I also had put on it. The body guy was supposed to be the best around, but his work is very lacking. Definitely do it, you will be impressed with the look. But do use an epoxy paste to bond this scoop to the factory hood. Hope this helps.
