I know, I have a spare set sitting in the back of my car right now...I see a whole lot of posts around on the subject, but no real evidence of whether they help, they are almost certainly better than the stock SRT4 cams though(which I'm pretty sure chrysler just used from the NA 2.4 motors) they have a somewhat higher powerband and more lift than all stock 2.4 cams except maybe the 96 2.4 cams(have an extra set of those too) I would use one of those sets myself except I thought I should get some use out of my #14s after what I paid for them, but check on neons.org or srt4forums.com for many many speculation threads with no real evidence
