I dug through a ton of threads on venting the stock BOV to the atmosphere, and it was about a 50/50 on whether or not you needed a filter on the stock BOV when you do that. Finally, I figured, from what people were saying, that it was in fact, something you want to have. But no where did anyone say what they used for a filter...do they make special filters just for that purpose? If not, I was looking at Crank Case Ventilation filters...theyre about the right size, and would probably do the trick nicely, but I cant find one at my local car parts store with a correct ID/OD on it, so they wont work too well, any ideas?

 

personally i wouldnt waste my money putting a filter on it. if your bov is sucking air in, then you have a big problem.

 

no filter here, no oil...nothing

 

k&n or any speed shop will have little filters for your piece of mind. not worth it imho

 

Currently have no filter, works just fine, thanks guys.

 

If you really want to put a filter on it, go to k & n web site and the p/n. then go to summit racing and enter the knn***** (*= k & n p/n) and get it. But I never had a filter on it.

 

I'd worry more about getting surge as a result of some POS restrictive little filter on there not allowing a fast enough vent, than I would be about sucking in something during the small amount of time that it is both open, and not expelling pressure. I've run FC's with open air bov's for years with never an issue. My FD also has the open air bov.
