Has anyone fitted an Ecotek CB-26P Valve to their A3/S3?
Supposedly it will increase performance, but more inportantly for me (because I use my S3 everyday) it claims to increase MPG figures.
After spending some time reading about it, I decided to go for the "Chrome Combo" version which includes a Piper Cross filter/silencer. At £85, I thought it has to be worth a bash - and the chrome finish will compliment my chrome AmD Viper DV!
Has anyone else tried one of these valves?
