I am installing a 034 MAF housing, ID 85mm, OD 89mm.
I was told the OD of the stock intake is also 89mm.

What hoses can I use?

a) RS4 accordion with 3.5" clamps?
b) someone said the stock accordion without O rings????
c) A straight 3.5" silicone hose? What length? Sources?

 

89mm is the OD of the billet MAF housing.
stock Y intake pipe.
Who sells a hose that fits?
Need to order.

 

MAF Hose, B5 RS4, Silicone Reinforced - 034Motorsport | Performance Parts for Audi, Porsche, and Volkswagen

ebay also carries them for less.

 

I thought the RS4 one would fit the 89mm MAF, but NOT the stock Y pipe?

 

the rs4 silicone and accordion hoses will be a little larger on the stock Y. I have the rs4 silicone hose and use a hose clamp on it.


this is an rs4 accordion between a 90mm maf and stock y-pipe. looks to be the oem o-rings in use.
