Hey guys. I was wondering if its possible to install a blow off valve on the stock turbo that comes with this A4? If so which ones to go with and how much does it cost?

Also is it possible to install a boost/turbo guage as well? Thanks

Cheers

 

Yes it is possible. Forge makes one but for your car, it is not optimal. An upgraded diverter valve is better in just about every way.

As for the boost gauge, we are a podi distributor and can get you a podi that looks OEM.

 

Hi,

Just a question to clarify, will the above void the warranty of the car?
