i am looking to get a bov for my 2000 1.8t a4 but I want the noise of a dump valve. I know these engines need a recirculating valve. This forge splitter one seems to do the job of not mucking up the way the engine runs but still produces the noise I'm looking for. I know this is a much talked about subject but was hoping anyone could let me know if this bov will definitely not cause any engine running problems from personal experience if possible as they are not cheap at 160 quid so wana make sure my car will still run ok before buying and fitting. Also how loud are they? And are there any other options out there?
