after i take out the airpump - ive seen some people put on filter breathers like little PCV breathers ---- do i do that? or what?



and if i do -- 9mm or 12mm

or do i just put on block off plates

if you are going to remove the airpump you might as well remove the acv as well,unless the car is an na and you still want to use the six ports, and block it off but if you dont want to do that then put a breather filter on the hose that goes to the acv.

yea --- i figured it out whne i posted my reply to my own question



status : drunk and looking in members gallery https://www.nopistons.com/forums/pub...#>/biggrin.png so thats how the question came up

Well if you have an N/a you only need to keep the air pump if you have an S5 car. If you have an S4 you can take it off.

On an S4, don't you need the air pump to pass emissions?

whats emmissions?

You are joking right? I don't see a smiley face or anything so maybe not.

Sure I am joking. I don't give a rats ass about emmissions. I have a full uncollected catless exhaust. https://www.nopistons.com/forums/pub...DIR#>/wink.png
