I like them, they provided a good power bump. I would like for them to be alittle more aggressive at idle but you can def tell there are cams in the car. I have a buddy that has a set of Custom L&M cams that lope their ass off!! but those are some high dollar versions. I also know that with the bigger cams they are having some issues with the timing chains and the added stress that it puts on them. so the JDM are a good compromise.
