Hey everyone, my buddy recently did the $2 dollar BOV mod on his 335i and I really like the way it sounds so I'm considering doing it too. I have all of the required materials sitting in my trunk ready to go but I want to get some more information before doing it. I know the big issue with this mod was the oil blow by. My friend got around this by putting filters at the end of the tubes. Does this setup look solid or should I just leave it alone and get a real cp+bov? I'm planning on getting a cp+BOV eventually but I kind of want to wait until my stock cp starts giving me issues or blows up. I want to do this mod just to have the cool sounds until then. What do you guys think? I'll attach a picture of my friends setup

Do it the right way and put a real CP BOV combo on. You will be you did.

you can just recap the back one and move the front diver valve hose down and around the power steering fluid, down to the driver side lower fender. It'll empty down to the lower fender where it'll eventually drain out rather then spray onto random parts of the engine. Eventually you want to install a oil catch can or something to collect the oil that could come out.

but if your running a stage 1 tune or higher, i would get the cp asap. When the stock charge pipe breaks, it'll leave you stranded and cost you that $30 c clip, which you will have to buy again for the new charge pipe.

Maybe a stupid question but if you take another 2 small 7/8" airfilters like the ones from OP picture and instead of capping off those 2 openings on the turbo inlets attach the 2 small airfilters on them, would that give better airflow to the turbos?

Maybe a good alternative for Mr.5 intake and people that want to keep the stock look.
