Ok I like my Ram Air but if I had to do it over again I think I would've got the rotofab last year instead of it. First of all Cervini's said they were going to send out crankcase filters for the Ram Air kit and they never did, but that wasn't a big deal I just went and bought one. Now my filter wants to fall out of the hole it goes in. I emailed them about it and they never emailed me back then I called them and the guy said he was about to send me a tech email right when I called. He said he would send that email and then I would just reply to it telling him the problem with some pictures. Well about 2 weeks has gone by and no tech email.
