all you need is a coke can mate
not hard at all and i think that there is a DIY thread somewhere
goodluck and it seriously takes 5 mins if that
unbolt the bov, cut a coke can and lay it flat, so you have a sheet of metal. then trace the bov on the coke can, and the bolt holes. cut out the holes for the bolts and put the can sheet in between the bov and the flange.....and bolt it all back up nice and tight.....presto u got flutters
