Just wondering if the benefits of installing a breather are worth it, if im correct the breather filter would go on the large metal line coming from the rear of the engine by the tb

 

IMO not worth it and doesn't work

 

The fitting on the rear valve cover is simply a fresh air source for the PCV system. Taking it from the filtered source of intake air or putting it's own filter really makes no difference.

 

It's a big BIG no-no for our cars... why? Because engine is DBW. Also it was a good mod 10 years ago for looks, but during that time, engines were mostly cable throttle. Technology changes, so does our mods.

 

What?!?!?! How does this have anything to do with DBW????? I removed my connection with the turbo install and had been running a small filter since. Now I have a catch can in between but it's still just a fresh air source to the crankcase.
