Hi have used a few different catch cans over the years, some completely useless, one home made and some good ones including the provent. I ended settling on the last 2 being HPD cans. They are great quality, filter well and have a dipstick for you check the oil level easily. Not cheap, around the same price as the provent but are cleanable as you don't have to replace the filter every 80k.
I have contacted HPD and they don't have one currently (bracket that is) but are looking for someone to drop their car in for a look. I live in WA so know where near Edwardstown SA. Is there anyone willing to drop their GC WK2 in discounted catch can.
I have no affiliation with HPD, just know they good quality products (had a intercooler for my pathfinder off them too). Contact them if interested?
