Sapper 157 Posted December 19, 2016 Share Posted December 19, 2016 (edited) I did a recent Weber swap, and I'm considering removing the ASV system. I have a question though that needs some expertise or previous experience. Will removing the ASV system hurt or damage my Catalyst converter? I wish I could remove it, but certain local laws prevent me from doing so. My understanding is that the ASV system pulls fresh air from the air cleaner into the catalyst converter. Will closing off that fresh air source hurt the catalyst converter? Has anyone done a weber swap on an EA 81 and not remove their catalyst converter, but did remove their ASV?

turbosubarubrat Posted December 19, 2016 Share Posted December 19, 2016 It wont hurt anything if you remove it. It's emissions equipment that isn't needed. Some ea81's don't even have them they just have a space plate with no threads in it. I deleted them and the car pasted DEQ with 243 thousand on it burning oil. 1 Quote Link to comment Share on other sites More sharing options...
