Do these actually make a difference in performance? Or if I buy these am I pretty much just throwing money away? Thanks in advance.

i hear there good

yes they do not any in the bottom end but about 8-10 in the top end.

I just installed them over the weekend, with the help of forum members One Eyed Willy and Tampa07GT (well, One Eyed Willy helped and Tampa07GT just stood there! :-)

I think it made a little bit of a difference, it's not a night and day change, but I could feel it pull a little harder. I'll know for sure in a couple weeks when I go back to the track.

I put mine on at the same time as my bbk intake and brenspeed tune so I dont know how much of a difference they make by themselves. However, my dyno numbers came out nicely.
