Install was easy. Can hear the turbo so much better




It fits B8 and B8.5 A4, A4 Allroad and A5 2.0T engines with a MAF sensor. It does not fit Gen3B engines without one.
No. It works on stock software, and pairs well with an iE ECU tune for the biggest gains.
Under an hour for most enthusiasts, with basic tools and no modifications.
Because this part doesn't currently comply with California emissions laws, we can't sell or ship it to California addresses. Everywhere else? Full send.
