Is it better or something??? Why two???
2.5 twin turbo- twin BOV:naughty:...
No. Only reason people do it is because they don't have anything to block off the stock BOV. You can't just get a rubber cap like a 7M. Well, one side you can, but the other side needs a block off plate which isn't as easy to get as a rubber cap, obviously. The stock one will almost never vent if you have an aftermarket one hooked up.
Or, some of the BOV kits just replace the stock BOV at the same location.
That's what I was mentioning in my first post. HKs made a kit that replaces the stock BOV and another that replaces the rubber hose that connects to the throttle body.
Up until recently, I was running a setup like this.
The ARC that replaces the stock BOV isn't actually hooked up but it has an integrated block off plate so I could remove the stock BOV. The HKS on the throttle body pipe was the working one. I sold the HKS though 'cause it's really annoying to me and just put the stock one back on... It's not as fragile as the stock 7M one and will be ok for now.
