i have a HKS "super blow off valve" for sale as pictured below but it has the 1/8 vac hose bit snapped off the end(plastic) .......still works fine it just opens too early for my liking personally.... this can be fixed quite easilly by someone who does plastic welding in your area as i have been told that it has been fixed before and is fixable again......its a perfect item otherwise makes a pssshhhhhh sound......comes with a adapter and mandrel bent ntakepipe that the adapter welds onto to suit a R32 gtst..... cost about 10 to 20 bucks to fix as good as new...... i want $180 for the lot......or may trade for bits of intrest...im open to offers.....
