All they have to do is add that plate to their stock BOV.............they come in a closed-loop recirculating setup from the factory.......so these srt folks don't have to spend so much to sound like an assclown
plus its a relatively small turbo, and the 2.4L spools that shit fasssst, so u can basically go into positive atmosphere at anytime other than idle. hence the constant blowing off.
actually, installing that spacer is a major pita. most people just add a aftermarket bov further downstream, and leave the stock one in place with the vacuum lines plugged.
[edit] i only know all this cuz my best friend has an srt4. in his defense, he's had a honda prelude, a well prepped civic, still has his autocross miata, and his wife drives an rx8.
