BiGMaC said:I view capping the exit on the BoVs as optional. I do have EBPF hotpipes. So appearance was good and I get a more audible Pffft, no turbo whine even running LMS v8. I do not have any evidence of oil, etc. under hood or or the BoV outlet ports (polished bright aluminum)... I question restricting thes ports personally. So I think optional for the filters.
BTW... Another reason I am researching utility of a catch can again before I install it.
That's why I wanted to confirm the K&N piece as well. I don't want to just leave the blow off valves sitting there wide open, but I wasn't sure if the K&N filters would restrict the ability to dump pressure.
