So I have been doing a little research and I have read all the threads that pertain to removing of these systems. The most common one is the one for removing these items from the the B6 and I have found a few for the B5 but not as detailed. Who has done this to their B5 and how is the car running and are you getting any cells from the removal of the sai?

Any pictures from B5 owners with this mod would be greatly appreciated with any details would be nice, I am considering doing this and I have already done a lot with the addition of a catch can so I have a little collection of parts. We do not have smog inspections here in NM but I still don't want to throw cells.

One of the main reason I ask is because since I redid my oil catch can and made the hose run shorter to the crank case adapter, I seem to get a lot more vapor fumes and I don't want to have to deal with a cell for removing the SAI system or any of the other vac systems.

Pictures of oil catch can .......

Fred- I am running literaly zero evap system in my A4. I just tore it all out and plugged the lines. So far, all I have is a CEL (but what's new?)

For the crankcase breather, I am running a 1" silicon line to my catch can.

I read somewhere that when you remove the SAI, it effects your gas mileage, is this true? Also, did any of you guys keep your stuff as it will be near impossible to sell a car in this condition. Not saying I'm going to do it but you never know, and it would need to be put back to this condition to sell.

The only flashing light I have in my cluster now is from the immobilizer as my cluster is from the UK and their cars of the same year came equipped with them. (The car with the key near the 7k on the rpm)

Part of Doc's car lives on ......... [:D]

Is that the ebay catch can? I was thinking about picking one up, how does it work?

No effect on gas mileage when I removed my PCV system. 31Mpg+ on freeway, 26-29Mpg Avg depending on how aggressive I drive.

Also my car idles weird when I start it, vibrates until it gets to normal ~800 rpms(maybe another problem since I get a running lean code and a misfire code. I Think I need new coil packs and a MAF) Other than that runs great.


And yes I know my engine bay is dirty. That's my next project. Along with figuring out why I have a AUG head.
