What is up with this 4AC???

[Criard]

question 1) what is the purpose of that breather filter on the head??? normally there's a rubber line (like to the left) connected from somewhere to there.


2) why is the top of the air filter housing upside down???

the breather filter is really just a "show" mod. alot of 4ac owners flip the air filter cover upside down, because they think it gives them added horsepower due to added airflow. i doubt it does anything, as its a 80 hp, emissions engine. you gain noise though...

I know this post is over a year old but i was flipping threw pages reading stuff, but the air cleaner being upside down actully makes the car slower.

The rubber line you are referring to goes from the valve cover to underneath the air cleaner. And i have to say ditto to the filter being just for show.
