Breather filter.

[CoreyS13]

I've heard many mixed things about this and searching came up to be confusing as well. If you throw a breather filter on the T off on the sr20det valve cover will it not do anything cause lack of vacuum or is a filter alone efficient?

It will get clogged with oil, especially if the motor in question an s13 sr. Just buy an oil catch can and run one of its hoses to the front of the T then its other hose to the crankcase breather port on your intake tube; Problem solved.
